be fruitful and multiply

This is God's blessing. He told Noah and his family to produce more humans like themselves, so that there would be many of them. The word "multiply" explains how they are to be "fruitful." See how you translated this in Genesis 1:28. (See: rc://en/ta/man/translate/figs-doublet and rc://en/ta/man/translate/figs-idiom)
