The mountains melted from before the Lord
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.
