Amos 4

Amos 4:11

"I overthrew you, as God overthrew Sodoma and Gomorrha, and you⌃ became as a brand plucked out of the fire: yet not even thus did you⌃ return to me, says the Lord."
Does Amos 4:10-12 imply that 'God' and 'the Lord' are two separate entities?

> Amos 4:10-12
> I have sent among you the pestilence after the manner of Egypt: your young men have I slain with the sword, and have taken away your horses; and I have made the stink of your camps to come up unto your nostrils: yet have ye not returned unto me, saith the LORD. I have overthrown some of you, as God overthrew Sodom and Gomorrah, and ye were as a firebrand plucked out of the burning: yet have ye not returned unto me, saith the LORD. Therefore thus will I do unto thee, O Israel: and because I will do this unto thee, prepare to meet thy God, O Israel.

This passage is taken by skeptics to mean that "God" and "the Lord" are two separate entities. This objection fails to appreciate the theological distinction between "Yahweh" (the covenant name of the God of Israel) and "Elohim" (a power and majesty general name and noun).
