The leaders and scholars of Jesus' time had first enslaved themselves to the law. This not only enhanced their prestige in society, it also gave them a sense of security. Man fears the responsibility of being free. It is often easier to let others make the decisions or to rely upon the letter of the law. Some men want to be slaves. After enslaving themselves to the letter of the law, such men always go on to deny freedom to others. They will not rest until they have imposed the same oppressive burdens upon everyone (Matt 23:4,15).
