'Burden' in the Bible

in order that this prediction of the Prophet Isaiah might be fulfilled, "He took on Him our weaknesses, and bore the burden of our diseases."

For my yoke is easy, and my burden is light.

Saying, These last have wrought but one hour, and thou hast made them equal unto us, which have borne the burden and heat of the day.

Tell Daughter Zion,“Look, your King is coming to you,gentle, and mounted on a donkey,even on a colt,the foal of a beast of burden.”
