Habakkuk 3:4

And [his] brightness was as the light; he had horns [coming] out of his hand: and there [was] the hiding of his power.

Ver. 4. And his brightness was as the light] The glory of the Lord was as a devouring fire on the top of the mountain, Exodus 24:17; the noonday light, the sun in his strength was nothing to this incomparable brightness, which was as the light, or as the sun, see Job 31:26; Job 37:20. Hence the heathens called Apollo or the sun Orus (which is the word here used), hence also the Greek οραω, to see (אור).

He had horns coming out of his hand] Or, bright beams out of his side, as the sun hath: "The eyes of the Lord are in every place," Proverbs 16:3, and every man before him is all window, Job 34:22; the whole world is to him as a sea of glass, Revelation 4:6, a clear transparent body, he shines and sees through it. God's hand or side is said to be horned in the sense that Moses's face was, Exodus 34:30 .

And there was the hiding of his power] Not the revealing of it, but velamen, symbolum, integumentum, the veil, the cover, such as God put over him when he showed Moses his glory. He could see but his back parts, and live; we need see no more that we may live. God is invisible, incomprehensible, and dwelleth in light unapproachable. How little a thing doth man here understand of God, Job 26:14; the greatest part of that which he knoweth is but the least part of that which he knoweth not. Surely as a weak eye is not able to behold the sun, no, nor the strongest eye without being dazzled; we cannot look upon it in rota, in the globe but only in radiis, into the rays; so here we cannot see God in his essence, but only in his effects, in his works, and in his Word, where also we have but a show, but a shadow of him, we see but his train in the temple, as Isaiah; the holy angels cover their faces with their wings as with a double scarf before God's brightness, which would put out their eyes else, Isaiah 6:2; see Psalms 104:2 1 Timothy 6:16 .
