'Children of Israel' in the Bible

All this is because of the wrongdoing of Jacob and the sins of the children of Israel. What is the wrongdoing of Jacob? is it not Samaria? and what are the high places of Judah? are they not Jerusalem?

Then give ear to this, you heads of the children of Jacob, you rulers of the children of Israel, hating what is right, twisting what is straight.

For this cause he will give them up till the time when she who is with child has given birth: then the rest of his brothers will come back to the children of Israel.
