Charles Spurgeon Commentary Habakkuk 2:5

"Yea, moreover, wine is treacherous, a haughty man, that keepeth not at home; who enlargeth his desire as Sheol, and he is as death, and cannot be satisfied, but gathereth unto him all nations, and heapeth unto him all peoples." — Habakkuk 2:5 (ASV)

This was spoken of the Chaldeans. They were an ambitious nation, so exceedingly greedy that it seemed as if the whole world would not be large enough to satisfy their voracious appetite. Their great kings enlarged their mouths like Gehenna, and they seemed as insatiable as the very maw of death itself.

They heaped up nation upon nation to make a huge empire for themselves.
