'Perpetually' in the Bible

The thigh offered by lifting up and the breast offered by waving they shall bring along with the offerings by fire of the portions of fat, to present as a wave offering before the Lord; so it shall be a thing perpetually due you and your sons with you, just as the Lord has commanded.”

The Lord said to him, “I have heard your prayer and your supplication, which you have made before Me; I have consecrated this house which you have built by putting My name there forever, and My eyes and My heart will be there perpetually.

For now I have chosen and consecrated this house that My name may be there forever, and My eyes and My heart will be there perpetually.

Without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, he remains a priest perpetually.
