Matthew 20:15

Is it not lawful...? — The question is not that of one who asserts an arbitrary right; it appeals tacitly to a standard which none could question. As far as the labourer was concerned, the householder had a right to give freely of what was his own. He was responsible to God only. In the interpretation of the parable, God was Himself the Householder, and men ought to have sufficient faith in Him to accept the gifts to some which wrought no wrong to others as in harmony with absolute righteousness.

Is thine eye evil? — The “evil eye” was, as in Proverbs 28:22, that which looked with envy and ill will at the prosperity of others. In Mark 7:22, it appears among the “evil things” that come from the heart. Popularly, as the derivation of the word “envy” (from invidere) shows, such a glance was thought to carry with it a kind of magic power to injure, and was to be averted, in the superstitious belief which still lingers in the East and many parts of Europe, by charms and amulets.
