'House of Israel' in the Bible

He hath remembered his loving-kindness and his faithfulness toward the house of Israel: all the ends of the earth have seen the salvation of our God.

Jehovah hath been mindful of us: he will bless, he will bless the house of Israel; he will bless the house of Aaron;

House of Israel, bless ye Jehovah; house of Aaron, bless ye Jehovah;
