Verse 1
Psalm 4:1-8. On Neginoth, that is, stringed instruments, as the kind of musical accompaniment. On other parts of title, see-on Introduction., The historical occasion was probably the same as that of the foregoing [see on Psalm 3:1, Title]. The writer, praying for further relief, admonishes his enemies of the vanity of attacking God‘s servant, exhorts them to repentance, and avows his confidence and peace in God‘s favor.
Hear — as in Psalm 3:4.
God of my righteousness — or, “my righteous God, as my holy hill” (Psalm 2:6), who will act towards me on righteous principles.
thou hast enlarged — expresses relief afforded in opposition to “distress,” which is expressed by a word denoting straits or pressure. Past favor is a ground of hope for the future.
Verse 2
sons of men — men of note or prominence (compare 2 Chronicles 21:9).
turn my glory — or, “royal dignity.”
into shame — or, “reproach.”
vanity — a foolish and hopeless enterprise (Psalm 2:1).
leasing — a lie.

godly — an object as well as subject of divine favor (compare Psalm 105:14, Psalm 105:15).

Verse 5
Not only repent, but manifest penitence by sacrifices or righteousness or righteous sacrifices, etc.

Contrast true with vain confidence.
light of thy countenance upon us — figure for favor (Numbers 6:26; Psalm 44:3; Psalm 81:16).

increased — an abundant harvest giving great joy (Isaiah 9:3).
