'Eternal' in the Bible

The sons of Aaron, the priests, will blow on the trumpets; this will be an eternal decree for your generations.

[For] the assembly, there will be one decree for you and for the alien who dwells [among you]; [it is] an eternal decree for [all] your generations. {You as well as the alien} will be {before Yahweh}.

Yahweh spoke to Aaron, "Behold, I myself have given to you the responsibility of my contributions for all the holy objects of the {Israelites}; I have given them as a portion to you and your sons as an eternal decree.

This [is also] for you: the contribution of their gift of the wave offerings of the children Israel. I have given them to you and your sons and your daughters with you as an eternal decree; whoever [is] clean in your house may eat it.

All the contributions of holiness that the {Israelites} offer to Yahweh I have given to you and your sons and your daughters with you as an eternal decree; it [is] an eternal covenant of salt {before} Yahweh to you and your offspring with you."

The Levites will perform the service of the tent of assembly, and they will bear their guilt, an eternal decree for all your generations. But they will not receive an inheritance in the midst of the {Israelites}

The one who gathers the ashes of the heifer will wash his garments; he will be unclean until evening. It will be an eternal decree for the {Israelites} and for one who dwells as an alien in their midst.

" 'It will be an eternal decree for them. The one who spatters the waters of impurity will wash his garments, and the one who touches the waters of impurity will be unclean until the evening.

and it will be for him and his {offspring} after him a covenant of an eternal priesthood because he was jealous for his God and made atonement for the {Israelites}.'"

and with the finest things of [the] ancient mountains, and with [the] choice things of [the] {eternal hills},

They are afraid of heights, and terrors [are] on the road. The almond tree blossoms, and the grasshopper draws itself along, and desire fails because man goes to his eternal home, and the mourners go about in the streets.

And who [is] like me? Let him proclaim [it]! And let him declare it and set it in order for me {since I established an eternal people} and things that are to come, and let them tell them [the things] that are coming.

And you said, "I shall be an eternal mistress forever!" You did not set these [things] upon your heart; you did not remember its end.

Hear, O mountains, the indictment of Yahweh, and you eternal foundations of the earth, for Yahweh has an indictment against his people, and against Israel he contends.
