Every priest and every christian has his place in the work of God, in the body of Christ

So they were put into their different groups, to take their places in the house of the Lord, in agreement with the rules made by Aaron their father, as the Lord, the God of Israel, had given him orders.
1 Chronicles 24:19

1)Rom 12:4 For, as we have a number of parts in one body, but all the parts have not the same use,
Rom 12:5 So we, though we are a number of persons, are one body in Christ, and are dependent on one another;
Rom 12:6 And having different qualities by reason of the grace given to us, such as the quality of a prophet, let it be made use of in relation to the measure of our faith;
Rom 12:7 Or the position of a Deacon of the church, let a man give himself to it; or he who has the power of teaching, let him make use of it;
Rom 12:8 He who has the power of comforting, let him do so; he who gives, let him give freely; he who has the power of ruling, let him do it with a serious mind; he who has mercy on others, let it be with joy.
2)1Co 12:12 For as the body is one, and has a number of parts, and all the parts make one body, so is Christ.
1Co 12:13 For through the baptism of the one Spirit we were all formed into one body, Jews or Greeks, servants or free men, and were all made full of the same Spirit.
