'Offspring' in the Bible

I will cast you out of My sight, as I have cast out all your brothers, all the offspring of Ephraim.

‘Fear not, O Jacob My servant,’ declares the Lord,‘And do not be dismayed, O Israel;For behold, I will save you from afarAnd your offspring from the land of their captivity.And Jacob will return and will be quiet and at ease,And no one will make him afraid.

“If this fixed order departsFrom before Me,” declares the Lord,“Then the offspring of Israel also will ceaseFrom being a nation before Me forever.”

Thus says the Lord,“If the heavens above can be measuredAnd the foundations of the earth searched out below,Then I will also cast off all the offspring of IsraelFor all that they have done,” declares the Lord.

“But I have stripped Esau bare,I have uncovered his hiding placesSo that he will not be able to conceal himself;His offspring has been destroyed along with his relativesAnd his neighbors, and he is no more.
