I am weary with my groaning; all the night make I my bed to swim; I water my couch with my tears.

Wesley's Notes

6:6 With my tears - It well becomes the greatest spirits to be tender, and to relent under the tokens of God's displeasure. David who could face Goliath himself, melts into tears at the remembrance of sin, and under the apprehension of Divine wrath, and it is no diminution to his character.

King James Translators' Notes

all...: or, every night

Jamieson-Fausset-Brown Bible Commentary

6. By a strong figure the abundance as well as intensity of grief is depicted.

Matthew Henry's Concise Commentary

6:1-7 These verses speak the language of a heart truly humbled, of a broken and contrite spirit under great afflictions, sent to awaken conscience and mortify corruption. Sickness brought sin to his remembrance, and he looked upon it as a token of God's displeasure against him. The affliction of his body will be tolerable, if he has comfort in his soul. Christ's sorest complaint, in his sufferings, was of the trouble of his soul, and the want of his Father's smiles. Every page of Scripture proclaims the fact, that salvation is only of the Lord. Man is a sinner, his case can only be reached by mercy; and never is mercy more illustrious than in restoring backsliders. With good reason we may pray, that if it be the will of God, and he has any further work for us or our friends to do in this world, he will yet spare us or them to serve him. To depart and be with Christ is happiest for the saints; but for them to abide in the flesh is more profitable for the church.
