Isaiah 48:1

The Lord Appeals to the Exiles

48:1 Listen to this, O family of Jacob,

you who are called by the name ‘Israel,’

and are descended from Judah,

who take oaths in the name of the Lord,

and invoke the God of Israel –

but not in an honest and just manner.

Jeremiah 4:2

4:2 You must be truthful, honest and upright

when you take an oath saying, ‘As surely as the Lord lives!’

If you do, the nations will pray to be as blessed by him as you are

and will make him the object of their boasting.”

Warning to Judah: Do Not Join in Israel’s Apostasy!

do not let Judah become guilty!

Do not journey to Gilgal!

Do not go up to Beth Aven!

Do not swear, “As surely as the Lord lives!”
