'Burden' in the Bible

And Moses said to the Lord, "Why have you afflicted your servant? Why have I not found favor in your sight, that you lay the burden of this entire people on me?

Then I will come down and speak with you there, and I will take part of the spirit that is on you, and will put it on them, and they will bear some of the burden of the people with you, so that you do not bear it all by yourself.
