Isaiah 48:1-2

New Revised Standard Version Catholic Edition

48 Hear this, O house of Jacob,
    who are called by the name of Israel,
    and who came forth from the loins^[a] of Judah;
who swear by the name of the Lord,
    and invoke the God of Israel,
    but not in truth or right.
² For they call themselves after the holy city,
    and lean on the God of Israel;
    the Lord of hosts is his name.
