Charles Ellicott Commentary Psalms 31:19

"Oh how great is thy goodness, Which thou hast laid up for them that fear thee, Which thou hast wrought for them that take refuge in thee, Before the sons of men!" — Psalms 31:19 (ASV)

Laid up. —Better, hidden, (Hebrew tsaphan; compare Psalms 17:14; Obadiah 1:6), as a treasure for the faithful, and now brought out and displayed in the presence “of the sons of men.”
