For God is the King of all the earth: sing ye praises with understanding.
For God is the King of all the earth - and shall be manifested as such after His final interposition for Israel (Zechariah 14:1-9).
Sing ye praises with understanding - (1 Corinthians 14:15-16.) Or, as the Hebrew 'Maschil,' is usually translated instruction, we may translate, 'Sing ye praises with edification'-spiritual 'wisdom.' Compare Colossians 3:16.
