'Burden' in the Bible

And Aaron hath finished -- his sons also -- covering the sanctuary, and all the vessels of the sanctuary, in the journeying of the camp, and afterwards do the sons of Kohath come in to bear it, and they do not come unto the holy thing, that they have died; these things are the burden of the sons of Kohath in the tent of meeting.

but this do to them, and they have lived, and do not die in their drawing nigh the holy of holies: -- Aaron and his sons go in, and have set them, each man to his service, and unto his burden,

This is the service of the families of the Gershonite, to serve -- and for burden,

'By the command of Aaron and his sons is all the service of the sons of the Gershonite in all their burden, and in all their service; and ye have laid a charge on them concerning the charge of all their burden.

And this is the charge of their burden, of all their service in the tent of meeting; the boards of the tabernacle, and its bars, and its pillars, and its sockets,

and the pillars of the court round about, and their sockets, and their pins, and their cords, of all their vessels, and of all their service; and by name ye do number the vessels of the charge of their burden.

from a son of thirty years and upward even unto a son of fifty years, every one who is going in to do the work of the service, even the service of burden in the tent of meeting,

by the command of Jehovah hath one numbered them, by the hand of Moses, each man by his service, and by his burden, with his numbered ones, as Jehovah hath commanded Moses.

And Moses saith unto Jehovah, 'Why hast Thou done evil to Thy servant? and why have I not found grace in Thine eyes -- to put the burden of all this people upon me?

and I have come down and spoken with thee there, and have kept back of the Spirit which is upon thee, and have put on them, and they have borne with thee some of the burden of the people, and thou dost not bear it thyself alone.
