The Lord also thundered in the heavens - Thunder is often in the Scriptures described as the voice of God. See the magnificent description in Psalms 29:1-11; compare Job 40:9, “Canst thou thunder with a voice like him?” So 1 Samuel 7:10; 1 Samuel 12:18; Psalms 77:18; Job 37:4.
And the Highest gave his voice - God, the most exalted Being in the universe, uttered his voice in the thunder; or, the thunder was his voice.
Hail-stones, and coals of fire - Accompanying the thunder. The repetition seems to be because these were such striking and constant accompaniments of the storm.
