John Gill's Bible Commentary Ver. 5. The mountains melted from before the Lord , etc.] The inhabitants of them, through fear, the Lord going before Israel in a pillar of cloud and fire, and delivering mighty kings and their kingdoms into their hand: [even] that Sinai from before the Lord God of Israel ; or, “as that Sinai”, the note of similitude being wanting; and the sense is, the mountains melted, just as the famous mountain Sinai in a literal sense did, when it trembled and quaked at the presence of God on it; the tokens of it, the fire and smoke, thunders, lightnings, and tempests there seen and heard; and which being observed, would call to mind the benefit Israel then received, which required praise and thankfulness, as well as would serve to express the awe and reverence of God due unto him.
Matthew Henry Commentary
Verses 1-5 - No time should be lost in returning thanks to the Lord for his mercies for our praises are most acceptable, pleasant, and profitable, when they flow from a full heart. By this, love and gratitude would be mor excited and more deeply fixed in the hearts of believers; the event would be more known and longer remembered. Whatever Deborah, Barak, or the army had done, the Lord must have all the praise. The will, the power, and the success were all from Him.
