Genesis 4:26

And Seth had a son, and he called his name Enos: he hoped to call on the name of the Lord God.

And to Seth, to him also there was born a son; and he called his name Enos: then began men to call upon the name of the Lord.

A son was also born to Seth, and he named him Enosh. At that time men began to call on Yahweh’s name.
