Please I want clarification on ye shall die like mere men, after God creating as in His own image.
Being created in God's image does not mean being created in the physical sense. Rather, it means that humans have intelligence, can reason, make choices, rational and have a moral consciousness or a knowledge or right and wrong, of good and evil.
The context of Psalm 82 is that God stands in His own congregation and judges in the midst of the rulers/judges. Psalm 82:1-2. In other words, God is outlining the fact that these "elohiym" "judge," who act on behalf of God are corrupt in their judgment.
At verse 6 God says, Sure, I said "You are gods, And all of you are sons of the Most High, verse 7, Nevertheless or However and by contrast, they will die like the men they are despite their power and authority.
It should be noted that these judges are "NOT" actual ontological deities claimed by some organizations and others who believe men can become gods, or even are gods.
“I said, “You are gods, sons of the Most High, all of you; nevertheless, like men you shall die, and fall like any prince.”” Psalm 82:6-7
While there are those who will claim that humans were also referred to as elohim, the Bible never calls any human an elohim. Moses was said to be like an elohim to pharoah Exodus 4:16. The passages with the elohim, which in translation, speaks of judges puts the emphasis on the men being the judges but the Hebrew, especially in other similar passages puts the emphasis on God being the judge Exodus 21:6, 22:8-9. The spirit that the woman with familiar spirits called from the dead was referred to as an elohim 1 Samuel 28:13 but while it’s debatable it was Samuel, it certainly wasn’t a human.
Jesus was accused of claiming to be god though he was clearly a human. That adds to the argument that no one believed, nor claimed humans were an elohim
“The Jews answered him, “It is not for a good work that we are going to stone you but for blasphemy, because you, being a man, make yourself God.” Jesus answered them, “Is it not written in your Law, ‘I said, you are gods’? If he called them gods to whom the word of God came—and Scripture cannot be broken—” John 10:33-35
The word of God came to those whom God was addressing in Psalm 82. They were called elohim. They were placed over the nations to judge the nations as described in Deuteronomy 32:8 DSS,LXX which is described in Psalm 82:2-5 as being their duty.
The leaders in Jesus’ time did not see it possible for men to be elohim. They also didn’t want to acknowledge any other gods either. Jesus was making the point that there are many elohim, not just one. And that God has many He calls sons. Jesus went forward not just claiming to be one of the elohim (benei ha’Elohim) but God incarnate.
“but if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me and I am in the Father.”” John 10:38
Verse 7 OP’s dilemma.
If these were men, there would be no punishment telling them they will die like men, for men already die. If instead they were heavenly beings as all the OT passages depicts every elohim, then telling them they will die like men was indeed a punishment especially seeing they were immortal.
