Isaiah 65:16

65:16 Whoever pronounces a blessing in the earth

will do so in the name of the faithful God;

will do so in the name of the faithful God.

I will no longer think about them.

Jeremiah 12:16

12:16 But they must make sure you learn to follow the religious practices of my people. Once they taught my people to swear their oaths using the name of the god Baal. But then, they must swear oaths using my name, saying, “As surely as the Lord lives, I swear.” If they do these things, then they will be included among the people I call my own.
