Psalms 24:4 - Joseph Benson’s Commentary on the Old and New Testaments

He that hath clean hands Whose actions and conversation are holy and unblameable. It is here very observable that the character of a right and acceptable worshipper of God is not taken from his nation and relation to Abraham; nor from any or all of those costly and laborious rites and ceremonies of the law in which the generality of the Israelites placed their confidence, but from moral and spiritual duties, which most of them grossly neglected. And a pure heart Purged from hypocrisy, and corrupt desires and designs, and careful to approve itself to God, as well as men, ordering a man's very thoughts, intentions, and affections, according to God's word. This is fitly added, because a man may keep his hands clean, in a good measure, from mere worldly motives, and without any respect to God, and even with an evil design. Who hath not lifted up his soul unto vanity Who doth not worship idols, often called vanities in Scripture, and who doth not value or desire the vain things of this life, such as honour, riches, pleasures; but who makes God his portion. And this, also, is very fitly mentioned as essential to the character of a truly good man, because, hereby he is distinguished from all carnal and ungodly men whatsoever, whose inseparable property it is, according to both the Old and New Testament, to love vanity, and to set their hearts chiefly upon the things of this world. Whereas good men are everywhere described to be such as seek their happiness in God, and prize and desire his favour and service infinitely more than all the enjoyments or this life; yea, even than life itself. Nor sworn deceitfully Hebrew, למרמה, lemirmah, unto, or with deceit, that is, falsely, or with a purpose of deceiving others thereby. Under this negative the contrary affirmative is included, namely, that he is one who, when he is called to swear, doth swear in truth, in judgment, and in righteousness, Jeremiah 4:2.
