'House of Israel' in the Bible

Hear this word which I take up for you as a funeral song, O house of Israel:

For thus says the Lord God,“The city which goes forth a thousand strongWill have a hundred left,And the one which goes forth a hundred strongWill have ten left to the house of Israel.”

For thus says the Lord to the house of Israel,“Seek Me [search diligently for Me and regard Me as more essential than food] so that you may live.

“Did you bring Me sacrifices and grain offerings during those forty years in the wilderness, O house of Israel? [Certainly not!]

Woe (judgment is coming) to those who are at ease and carefree in Zion (Judah)And to those on the mountain of Samaria who feel secure,The distinguished men of the foremost of nations,To whom the house of Israel comes.

“For behold, I am going to stir up a nation against you,O house of Israel,” says the Lord, the God of hosts,“And they will afflict and torment you [to the entire limits of Israel] from the entrance of Hamath [in the north]To the brook of the Arabah [in the south].”

Then Amaziah, the priest of Bethel [site of the golden calf shrine], sent word to Jeroboam king of Israel, saying, “Amos has conspired against you in the midst of the house of Israel; the land is unable to endure all his words.

“For behold, I am commanding,And I shall shake and sift the house of Israel among all nations [and cause it to tremble]Like grain is shaken in a sieve [removing the chaff],But not a kernel [of the faithful remnant] shall fall to the ground and be lost [from My sight].
