'Services' in the Bible

until [the time when] there arose another king over egypt who did not know joseph [nor his history and the merit of his service to Egypt].

Do you not know that those who officiate in the sacred services of the temple eat from the temple [offerings of meat and bread] and those who regularly attend the altar have their share from the [offerings brought to the] altar?

It was revealed to them that their services [their prophecies regarding grace] were not [meant] for themselves and their time, but for you, in these things [the death, resurrection, and glorification of Jesus Christ] which have now been told to you by those who preached the gospel to you by the [power of the] Holy Spirit [who was] sent from heaven. Into these things even the angels long to look.

These things I have written to you who believe in the name of the Son of God [which represents all that Jesus Christ is and does], so that you will know [with settled and absolute knowledge] that you [already] have eternal life.
