'Offspring' in the Bible

you are to present to the Lord every firstborn male of the womb. All firstborn offspring of the livestock you own that are males will be the Lord’s.

Remember Your servants Abraham, Isaac, and Israel—You swore to them by Your very self and declared, ‘I will make your offspring as numerous as the stars of the sky and will give your offspring all this land that I have promised, and they will inherit it forever.’”

The Lord spoke to Moses: “Go, leave here, you and the people you brought up from the land of Egypt, to the land I promised to Abraham, Isaac, and Jacob, saying: I will give it to your offspring.
