SEV Biblia, Chapter 18:5
porque le ha escogido el SEÑOR tu Dios de todas tus tribus, para que esté para ministrar al nombre del SEÑOR, él y sus hijos todos los días.
John Gill's Bible Commentary
Ver. 5. For the Lord thy God hath chosen him out of all thy tribes , etc.] That is, has chosen the tribe of Levi out of all the other tribes of Israel: to stand to minister in the name of the Lord ; the priests to minister to the Lord by offering sacrifices, and the Levites to minister to the priests in assisting them in their service; and both their ministry were in the name of the Lord, and for his glory, and done standing; for there was no sitting in the sanctuary f208 ; the priestly ministry was only performed standing f209 , whatever was done sitting was rejected f210 ; (see Hebrews 10:11), him and his sons for ever ; Levi and his posterity, or the posterity of the tribe of Levi, were chosen by the Lord to this service, to be employed in it as long as the ceremonial law continued, on which stood the Levitical priesthood; but both are now abolished by Christ, having their accomplishment in him, ( Hebrews 7:11 12:18).
Matthew Henry Commentary
Verses 1-8 - Care is taken that the priests entangle not themselves with the affair of this life, nor enrich themselves with the wealth of this world; the have better things to mind. Care is likewise taken that they want no the comforts and conveniences of this life. The people must provide for them. He that has the benefit of solemn religious assemblies, ought to give help for the comfortable support of those that minister in suc assemblies.
