Matthew 11:30
ESV - 30 For my yoke is easy, and my burden is light.
A yoke means work, as originally oxen were united together to farm land. Yokes meant heavy, hard work because the yokes themselves were heavy and wooden (crossbars) which were utilized to connect 2 oxen together to plow more efficiently than the one man behind the horse/ox idea. But Jesus is using a paradox here (which He loved/loves to do). Jesus contrasts the load of doing the Law with the light burden of obeying His teachings (with His help, of course). Help us, O Lord, Thy yoke to wear, Delighting in Thy perfect will; Each other’s burden learn to bear, And thus Thy law of love fulfill. --a hymn by Thomas Cotterill entitled, "More Blessed to Give Than to Receive"
