'Serve' in the Bible

But thou, appoint the Levites over the tabernacle of testimony, and over all the vessels thereof, and over all things that belong to it: they shall bear the tabernacle, and all its vessels; and they shall serve it, and round about the tabernacle shall they encamp;

And they shall take all the instruments of service, wherewith they serve in the sanctuary, and put them in a cloth of blue, and cover them with a covering of badgers' skin, and shall put them upon a pole.

from thirty years old and upward even to fifty years old, every one that came to serve in the work of the service, and in the work of carrying, in the tent of meeting,

And from fifty years old he shall retire from the labour of the service, and shall serve no more;

but he shall minister with his brethren in the tent of meeting, and keep the charge, but he shall not serve in the service. Thus shalt thou do unto the Levites with regard to their charges.

Make thee two trumpets of silver; of beaten work shalt thou make them; and they shall serve for the calling together of the assembly, and for the journeying of the camps.

And thy brethren also, the tribe of Levi, the tribe of thy father, bring near with thee, that they may unite with thee, and minister unto thee; but thou and thy sons with thee shall serve before the tent of the testimony.
