John Gill Commentary Amos 9:5

"For the Lord, Jehovah of hosts, [is] he that toucheth the land and it melteth, and all that dwell therein shall mourn; and it shall rise up wholly like the River, and shall sink again, like the River of Egypt;" — Amos 9:5 (ASV)

And the Lord God of hosts [is] he that touches the land, and
it shall melt
Which is another reason why it is impossible to escape the hands of a sin revenging God, because he is omnipotent as well as omniscient; he is the Lord of all the armies above and below; and if he but touch the land, any particular country, as the land of Israel, it shakes and trembles, and falls into a flow of water, or melts like wax; as when he touches the hills and mountains they smoke, being like fuel to fire; see (Psalms 104:32) (144:5) ; and all that dwell there shall mourn ;
their houses destroyed, their substance consumed, and all that is near and dear to them swallowed up: and it shall rise up wholly like a flood, and shall be drowned as [by]
the flood of Egypt; (See Gill on Amos 8:8).
