The first instruction or “commandment” God gave to the first people was, “Be fruitful and multiply; fill the earth and subdue it.” The same instruction was given after the flood, “ ... replenish the earth.”
I’m sure Mr. Feder was aware of these instructions, and was not confusing the events of Genesis with the Law given following the Exodus.
Yup. Being an observant Jew, odds are that Mr. Feder knew exactly what he was talking about.
