John Gill Commentary Psalms 94:22

"But Jehovah hath been my high tower, And my God the rock of my refuge." — Psalms 94:22 (ASV)

But the Lord is my defence
The defence of his church and people, of all the righteous, against those great armies of their enemies that gather together against them: the Targum, in the king's Bible is,

``the Word of the Lord shall be my weapon:''

and my God is the rock of my refuge ;
to whom recourse is had for shelter from the enemy, and against which the gates of hell cannot prevail: both characters, rock and refuge, agree with Christ, the essential Word of the Lord.
