New Defender's Study Bible Notes
15:1 who shall dwell. Compare Psalm 24:3. The specifications of righteousness listed in these two psalms could only really be met by Christ Himself. As Psalm 14 describes in some detail the characteristics of wicked men, so this psalm describes what would characterize the life of a righteous man.
15:5 usury. The law had rather severe restrictions against lending money at high interest rates (Deuteronomy 23:19,20; 24:10-13).
Psalm 16 (title) Michtam. The term “michtam” is applied also to Psalms 56–60. Its meaning seems to suggest meditation with deep feeling and significance.
