'Burdened' in the Bible

For we do not want you to be unaware, brethren, of our affliction which came to us in Asia, that we were burdened excessively, beyond our strength, so that we despaired even of life;

For indeed while we are in this tent, we groan, being burdened, because we do not want to be unclothed but to be clothed, so that what is mortal will be swallowed up by life.

If any woman who is a believer has dependent widows, she must assist them and the church must not be burdened, so that it may assist those who are widows indeed.
