'Burdened' in the Bible

'Come unto me, all ye labouring and burdened ones, and I will give you rest,

For we do not wish you to be ignorant, brethren, of our tribulation that happened to us in Asia, that we were exceedingly burdened above our power, so that we despaired even of life;

for we also who are in the tabernacle do groan, being burdened, seeing we wish not to unclothe ourselves, but to clothe ourselves, that the mortal may be swallowed up of the life.

If any believing man or believing woman have widows, let them relieve them, and let not the assembly be burdened, that those really widows it may relieve.
