It is difficult to translate the Hebrew of this verse. The RSV renders this line, “the man greedy for gain curses and renounces the Lord.” The word for “blesseth” occasionally means “to curse” (see on Job 1:5), but it is doubtful whether it has that meaning here. The word translated “covetous” comes from the Hebrew root meaning “to cut off,” hence “to make a large profit.” Jesus warned, “Beware of covetousness” (Luke 12:15). We tend to place emphasis on the sins of the flesh, forgetting that the acquisitive instinct may become as evil or perverted and unrestrained as carnal lust. Covetousness is idolatry (Col. 3:5; cf. Ex. 20:17). The evil man’s contempt for God is shown in the following verses.
His heart’s desire.
He boasts of the evil desires of his heart. He boasts that he gets all he desires.
