'Burdened' in the Bible

Come to me, all [of you] who labor and are burdened, and I will give you rest.

For we do not want you to be ignorant, brothers, concerning our affliction that happened in the [province of] Asia, that we were burdened to an extraordinary degree, beyond [our] strength, so that we were in despair even of living.

For indeed we who are in this tent groan, being burdened {for this reason, that} we do not want to be unclothed, but to be clothed, in order that what is mortal may be swallowed up by life.

If any believing woman has widows, she must help them, and the church must not be burdened, in order that it may help those [who are] truly widows.
