“Mild yoke” is an allusion to the Bible: “My yoke is easy, my burden is light” (Matthew 11:30). In the law of the Old Testament, Jewish people were required to follow over 600 strict religious laws. Jesus used this metaphor to relieve them of the burden of these laws. He claimed that there were only two laws man needed to follow: love God, love each other. Thus the “yoke” and “burden” of Jesus was both forgiving and “light.” To “bear his mild yoke” means to follow Jesus’s two commandments to love God and love each other.
