Genesis 6:1 describes a turning point in the early history of the world: human population has grown across the surface of the earth, and children, including daughters, are being born in increasing numbers. The verse is narration rather than a command or promise, so its job is to set the scene for what follows. It is written by Moses, traditionally regarded as the author of the Torah, and it is addressed to the people of Israel who are reading the story of their origins.

What Genesis 6:1 Means
The phrase “when men began to multiply” points to the growth of the human family after the flood-era genealogies in Genesis 5. The population is expanding, spreading across the land and forming larger communities. The author is describing ordinary, natural increase, the same blessing God first gave in Genesis 1:28 when he told humanity to be fruitful and multiply.
The words “daughters were born to them” are easy to skim past, but they matter. Scripture pays close attention to the full human family, and this detail sets up the events of the next few verses, which concern the relationships between different groups of people. The verse does not explain those events yet. It simply establishes the setting.
What the verse does not do is pass moral judgment or promise anything directly. It is a transition sentence. Its meaning becomes clearer only when read alongside the verses that follow, which describe the tension and corruption that grew as the population expanded.
The Context of Genesis 6:1
Genesis is the first book of the Torah, and in Jewish and Christian tradition it is attributed to Moses. It was written to shape the identity of a people who were learning where they came from and why the world looks the way it does. Its earliest readers were Israelites who needed to understand creation, human failure, and God’s faithfulness across generations.
Just before this verse, Genesis 5 lists the descendants from Adam down to Noah, marking the long line of human life. Just after it, verses 2 through 4 describe the “sons of God” taking wives and the “Nephilim” appearing on the earth, and God then limits the human lifespan to 120 years. Read in that setting, verse 1 is the opening of a warning. The growth of humanity is not condemned in itself, but the surrounding verses show that growth without faithfulness leads to trouble.
Key Phrases in Genesis 6:1
Genesis 1:28
God blessed them. God said to them, “Be fruitful, multiply, fill the earth, and subdue it. Have dominion over the fish of the sea, over the birds of the sky, and over every living thing that moves on the earth.”

This verse is the original blessing to be fruitful and multiply, given at creation. Reading it alongside Genesis 6:1 shows that the population growth described there is not a new development but the fulfillment of God’s first command, which sets the baseline for understanding what the later chapters reveal about human choices.
Genesis 6:5
The LORD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of man’s heart was continually only evil.
(WEB)
Genesis 6:5 follows the story of the expanding population with a sober assessment of human wickedness. Reading it with verse 1 helps you see that the growth described there is not neutral: the same generations that multiplied are also the ones whose hearts turned toward evil, which is why the narrative moves toward judgment and grace.
A Short Prayer From Genesis 6:1
Lord, you gave the first command to be fruitful and multiply, and you have watched the human family grow from the beginning. Help me to receive whatever growth you bring into my life with gratitude and with wisdom. Teach me to steward my families, work, and relationships in ways that honor you rather than my own pride. Keep my heart faithful as my responsibilities increase, and let every blessing point me back toward you. Amen.
