'Burden bearers' in the Bible

Solomon had 70,000 burden bearers (transporters) and 80,000 stonemasons in the hill country [of Judah],

and he maketh of them seventy thousand burden-bearers, and eighty thousand hewers in the mountain, and three thousand and six hundred overseers, to cause the people to work.

and over the burden-bearers, and overseers of every one doing work for service and service; and of the Levites are scribes, and officers, and gatekeepers.

And Judah saith, 'The power of the burden-bearers hath become feeble, and the rubbish is abundant, and we are not able to build on the wall.'
