Charles Ellicott Commentary Psalms 69:10

"When I wept, [and chastened] my soul with fasting, That was to my reproach." — Psalms 69:10 (ASV)

When I wept ... —The expression I wept (or lamented) my soul with fasting is hardly intelligible, though perhaps we might say I wept out my soul with fasting. The Septuagint and Psalm 35:13 suggest an emendation to I humbled my soul with fasting.

To my reproach. —Quite literally and better, a reproach to me. Those who made light of the covenant altogether, who were in heart apostates both to faith and patriotism, would naturally treat with contempt those outward signs by which an erring Israelite acknowledged his offence and sought reconciliation.
