'Descent' in the Bible

Now these were the ones who came up from Tel-melah, Tel-harsha, Cherub, Addan, and Immer, but they were not able to prove their fathers' household and their descent, if they were from Israel:

These were the ones who came up from Tel-melah, Tel-harsha, Cherub, Addon, and Immer, but they were not able to prove their ancestral houses or their descent, whether they were from Israel:

And Yahweh will cause the majesty of his voice to be heard, and he will cause the descent of his arm to be seen, in furious anger and a flame of devouring fire, [with] a cloudburst and a rainstorm and stones of hail.
