'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.

Therefore will he give them up, until the time that she which travaileth hath brought forth: then the remnant of his brethren shall return unto the children of Israel.
