'Everlasting' in the Bible

And he confirmed it to Jacob as a statute, an everlasting covenant to Israel,

Oh give thanks to Yahweh, for he [is] good; his loyal love [is] everlasting.

Blessed be Yahweh the God of Israel, from everlasting to everlasting!" Then all the people said, "Amen!" and praised Yahweh.

And with them [were] Heman and Jeduthun and the remainder of those chosen, who were designated by name to give thanks to Yahweh, for his loyal love [is] everlasting.

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