'Posterity' in the Bible

I will cast you out of My sight, as I have cast out all your brothers (relatives through Jacob), all the descendants of Ephraim.

For I have known the thoughts that I am thinking towards you -- an affirmation of Jehovah; thoughts of peace, and not of evil, to give to you posterity and hope.

‘Fear not, O Jacob My servant,’ says the Lord,‘Nor be dismayed or downcast, O Israel;For behold, I will save you from a distant land [of exile]And your descendants from the land of their captivity.Jacob will return and will be quiet and at ease,And no one will make him afraid.

Indeed, there is hope for your posterity. Your children will return to their own territory. I, the Lord, affirm it!

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

Against the land of Merathaim: Go up against it, and unto the inhabitants of Pekod, Waste and devote their posterity, An affirmation of Jehovah, And do according to all that I have commanded thee.
