David spoke of the night as bruising him ( Psalm 139:11) because it is often at night that harm comes to people. The only other places in the Old Testament where the Hebrew word sup, translated "overwhelm" (NASB) or "hide" (NIV), occurs are in Genesis 3:15 and Job 9:17 where the translation is "bruise." However, since darkness and light are the same to God, David felt secure always. Darkness does not hide things from God"s sight as it does from human eyes. [source][source][source]
