'Offspring' in the Bible

And you must say to them, 'Thus says the Lord Yahweh: "On the day of my choosing Israel {I swore} to the offspring of the house of Jacob, and I made myself known to them in the land of Egypt, and {I swore} to them, {saying}, 'I [am] Yahweh your God.'

And I defiled them through their gifts in sacrificing all of [the] first offspring of [the] womb, in order that I will cause them to be stunned, so that they will know that I [am] Yahweh.

And you must give to the Levitical priests who [are] from the offspring of Zadok, the [ones] [coming] near me," {declares} the Lord Yahweh, "to serve me, a bull, {a calf} as sin offering.

And a widow or divorced [woman] they shall not take for themselves as wives, {but only} a virgin from the offspring of the house of Israel, or the widow who is a widow for a priest they may take.
