And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD. And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering: But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell. Gen 4:3-5
Lev 22:29 And when ye will offer a sacrifice of thanksgiving unto the LORD, offer it at your own will.
King James Version with Strong's Numbers:
The real sense of the original writing was:
(KJV+) Yet they shall be1961 ministers8334 in my sanctuary,4720 having charge6486 at413 the gates8179 of the house,1004 and ministering8334 (853) to the house:1004 they1992 shall slay7819 (853) the burnt offering5930 and the sacrifice2077 for the people,5971 and they1992 shall stand5975 before6440 them to minister8334 unto them.
Note that "sharath" [Strong' #8334] from which "minister" is translated is also translated as "servant"; "zebach" [Strong's #2077] from which "sacrifice" is translated is also translated as "offering; the word "amad" [Strong's #5975] from which "stand" is translated is also translated as "stay"; and that "sharath" [Strong' #8334] from which the last "minister" is translated is also translated as "serve".
