'Everlasting' in the Bible

And hath confirmed the same to Jacob for a law, and to Israel for an everlasting covenant,

O give thanks to the Lord, for He is good;For His lovingkindness is everlasting.

May Yahweh, the God of Israel, be praisedfrom everlasting to everlasting.”Then all the people said, “Amen” and “Praise the Lord.”

With them were Heman and Jeduthun, and the rest who were chosen, who were designated by name, to give thanks to the Lord, because His lovingkindness is everlasting.

And you made your people Israel an everlasting nation for yourself. And you, O Yahweh, became their God.
