PRAYERS AND WORSHIP:
God's name and His character are inseparable, [Exod. 20:7.] Using His holy name lightly in a vain, empty manner is insulting and degrading. This could also be done by perjuring oneself in a court of law or by cursing.
The commandment applies to hypocritical worship, using God's name in meaningless prayer and praise [Is. 29:13].
True worship is that which occurred under the inspiration of God's Spirit [John 4:23-24; Phil. 3:3].
The sacrifice of the WICKED IS ABOMINATION.
Yahweh has given His unalterable PRONOUNCEMENT on the worship of the wicked. It is repulsive to Him, a stench, which means it stinks to His nostrils. The wicked attend to worship clothed in the garment of HYPOCRISY.
How much greater is the Lord's HATRED of those who bring sacrifices and in the same hour are plotting
some future wickedness.
