The Flood Begins: The Fountains Open and God Seals the Ark
11In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst open, and the sky’s windows opened.12It rained on the earth forty days and forty nights.13In the same day Noah, and Shem, Ham, and Japheth—the sons of Noah—and Noah’s wife and the three wives of his sons with them, entered into the ship—14they, and every animal after its kind, all the livestock after their kind, every creeping thing that creeps on the earth after its kind, and every bird after its kind, every bird of every sort.15Pairs from all flesh with the breath of life in them went into the ship to Noah.16Those who went in, went in male and female of all flesh, as God commanded him; then Yahweh shut him in.
Genesis 7:11–16 describes the onset of the Flood: the cosmic waters are released through burst fountains of the deep and opened sky-windows, raining forty days and nights, while Noah, his family, and pairs of all living creatures enter the ark together. God Himself personally seals the ark's door, shifting from impersonal judgment to intimate divine protection of those chosen for salvation.
God doesn't just command the flood—He personally closes the door, making rescue not a human project but an act of divine tenderness.
Commentary
Genesis 7:11 — The Dating and the Cosmic Rupture The narrator anchors the Flood with unusual chronological precision: the six-hundredth year of Noah's life, the second month, the seventeenth day. This is not decorative; it signals that what follows is history of cosmic significance, comparable in weight to the creation account itself (cf. Gen 1:1). The "fountains of the great deep" (Hebrew: tehom rabbah) recalls the tehom of Genesis 1:2, the formless watery chaos over which the Spirit hovered before creation. To say these fountains "burst open" (nivcqa'u) is to say the architecture of creation is cracking. Simultaneously, the "windows of the sky" (arubbot hashamayim) open — the floodgates holding back the waters above the firmament (cf. Gen 1:6–8). Together, these images portray the Flood not merely as heavy rainfall but as a reversal of the second and third days of creation: the separation of waters from waters is undone. The earth is returning, structurally, to the pre-creation state of Genesis 1:2.
Genesis 7:12 — Forty Days and Forty Nights The duration of forty days and nights is simultaneously literal and typologically resonant. In the Old Testament, "forty" consistently marks a period of intense divine testing and purification: Moses on Sinai (Ex 24:18), Elijah's journey to Horeb (1 Kgs 19:8), and most decisively, Israel's forty years in the wilderness. The New Testament consciously recapitulates this pattern in Jesus' forty days of fasting and temptation (Mt 4:2). The Church's forty days of Lent draws directly from this tradition. The Flood's forty days, then, is not merely meteorological data; it is the first great biblical instance of a divinely measured period of purgation and transformation.
Genesis 7:13 — The Entry Enumerated "In the same day" (Hebrew: b'etzem hayom hazeh) is a formulaic phrase used elsewhere in the Pentateuch for solemn, unrepeatable moments of covenant fulfillment (cf. Gen 17:23, Ex 12:41, 51). The careful listing of names — Noah, then his three sons Shem, Ham, and Japheth, then their wives — mirrors the genealogical structure of Genesis 5 and anticipates the Table of Nations in Genesis 10. The family is the unit of salvation here, which is theologically significant: Noah's righteousness carries a redemptive weight for those bound to him. This foreshadows the household baptisms of the New Testament (Acts 10:48; 16:15; 16:33) and the Church's teaching on the domestic church.
Genesis 7:14 — Every Creature After Its Kind The triple repetition of "after its kind" (leminehu) echoes the creation account of Genesis 1 (vv. 11, 12, 21, 24, 25), where the phrase appears as God calls forth species in ordered succession. In the midst of creation's undoing, the categories of created order are being preserved. The ark becomes, in effect, a floating Eden — a sanctuary where the original diversity and integrity of creation is held safe within wooden walls. This is significant for Catholic ecology and for the theology of creation: God's response to sin is not the annihilation of the natural order, but its rescue and eventual renewal.
Genesis 7:15 — The Breath of Life The phrase "breath of life" (nishmat chayyim) returns us directly to Genesis 2:7, where God breathes life into Adam. Every creature aboard the ark shares, in its own degree, in this divine gift. The ark preserves not just biological diversity but the very trace of God's creative breath in living things. St. Ambrose noted that this passage underscores the dignity of all animate creation as bearing, in some way, the mark of the Creator.
Genesis 7:16 — Yahweh Shuts the Door The final verse performs an extraordinary narrative and theological pivot. After a long catalogue of human and animal action — entering, pairing, proceeding — the subject suddenly becomes Yahweh. It is not Noah who closes the door. The use of the divine name Yahweh (rather than Elohim, more common in the surrounding Flood narrative) here is charged with intimacy and covenant faithfulness. The God who commands is also the God who completes, who personally seals the salvation of those who have trusted and obeyed. The sealed ark becomes a type of divine custody: those inside are not merely sheltered by wood, but held by God.
Catholic Commentary
Catholic tradition has consistently read the ark as a type of the Church, and these verses provide the doctrinal pivot on which that typology turns. St. Peter explicitly identifies the Flood as a figure of Baptism: "eight persons were saved through water. Baptism, which corresponds to this, now saves you" (1 Pet 3:20–21). St. Augustine, in The City of God (XV.26), elaborates that every dimension of the ark — its dimensions, its single door, its one window — prefigures the Body of Christ: outside the Church, there is no salvation, just as outside the ark there was none in the waters of judgment.
The Catechism of the Catholic Church explicitly affirms this typology: "The Church has seen in Noah's ark a prefiguring of salvation by Baptism, for by it 'a few, that is, eight persons, were saved through water'" (CCC 1219). The sealing of the ark by Yahweh in verse 16 finds its sacramental echo in the sphragis — the seal of the Holy Spirit conferred in Confirmation (CCC 1295–1296), by which the baptized are definitively "sealed" into Christ's protection.
The precise dating in verse 11 drew the attention of early Christian computists. Origen (Homilies on Genesis, II.3) observed that the seventeenth day of the second month, when counted forward in the lunar calendar, corresponds typologically to Passover/Resurrection timing — a remarkable alignment that the tradition has read as a providential foreshadowing of the Resurrection of Christ, who "descended into the waters" of death and emerged to new life.
St. John Chrysostom (Homilies on Genesis, 26) reflects at length on the act of God closing the door: this is not a mechanical lock but an act of divine tenderness — the Good Shepherd gathering and securing his own. The same imagery echoes in the Gospel of John (10:9), where Christ declares himself the Door through which the sheep enter and are kept safe.
For Today
Contemporary Catholics can draw a pointed spiritual lesson from the sequence of this passage: God commanded, Noah obeyed in every detail, and then — only then — God Himself sealed the door. There is a pattern here that speaks directly to modern anxieties about security and control. We are invited to do our part fully and faithfully, and then to trust that the final act of protection belongs to God, not to us. We cannot seal ourselves in.
This has immediate application in the Sacraments. Catholics often approach Baptism, Confirmation, and the Eucharist as formalities or social rites. But verse 16 insists that every sacramental sealing is Yahweh shutting the door — a personal, definitive act of divine guardianship over the soul. The ark's preservation of every creature "after its kind" also challenges Catholics to take seriously their responsibility for creation (cf. Laudato Si', §71), recognizing in biodiversity a reflection of God's creative breath.
Finally, the enumeration of Noah's household should prompt reflection on the family as the primary community of salvation. Catholic parents, like Noah, carry a representative spiritual weight: the faith they live, hand on, and embody becomes, by God's grace, an ark for those entrusted to their care.
