“And he said unto them, Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God.”
King James Version (KJV)
Matthew Henry's Concise Commentary
16:13-18 To this parable our Lord added a solemn warning. Ye cannot serve God and the world, so divided are the two interests. When our Lord spoke thus, the covetous Pharisees treated his instructions with contempt. But he warned them, that what they contended for as the law, was a wresting of its meaning: this our Lord showed in a case respecting divorce. There are many covetous sticklers for the forms of godliness, who are the bitterest enemies to its power, and try to set others against the truth.
“For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen it, repented not afterward, that ye might believe him.”
