'Burden' in the Bible

for my yoke is easy, and my burden is light.'

that These, the last, wrought one hour, and thou didst make them equal to us, who were bearing the burden of the day -- and the heat.

'Tell ye the daughter of Zion, Lo, thy king doth come to thee, meek, and mounted on an ass, and a colt, a foal of a beast of burden.'
