Be fruitful and multiply
In Judaism, Christianity, and some other Abrahamic religions, the commandment to "be fruitful and multiply" (referred to as the "creation mandate" in some Christian traditions) is the divine injunction which forms part of Genesis 1:28, in which God, after having created the world and all in it, ascribes to humankind the tasks of reproducing and filling the earth. After the flood, God repeats the same instruction to Noah and his sons: "Be fruitful and multiply and fill the earth".
