Hello Lj Han,
Firstly, it is important to read the context. In the CSB, it says in Psalm 82:6-8
“I said, ‘You are gods; you are all sons of the Most High. However, you will die like humans and fall like any other ruler.’ Rise up, God, judge the earth, for all the nations belong to you.”
Thus, it makes it very clear that these “gods” are inferior to the Most High, which is Yahweh: the God of Abraham, Isaac, and Jacob; the God of Israel.
The word translated as “gods” (and God, too, ironically) is the Hebrew elohiym. This word can mean gods, the supreme God (Yahweh,) angels, rulers, or judges. In any case, it is persons with power.
So then, if you read the entire psalm, which of those would make the most sense? Who would be judging unjustly and showing partiality to the wicked (verse 2?) Who does not know or understand; but wanders in darkness (verse 5?) Who would die like humans and fall like any other ruler (verse 7?) It would make sense that the answer would be rulers or judges, such as kings (who did both.)
It is good to keep in mind that in the ancient world, kings sometimes did claim godhood. The Egyptian Pharaoh did and the Roman Ceasar did. However, this Psalm proclaims that they will die like mere humans (because they are mere humans) and like other rulers (perhaps bringing to mind the kings and rulers they conquered.)
Jesus refers to Psalm 82:6 in John 10:34 when he is accused of blasphemy: of saying he is God. And in any other context, one would be blaspheming. But Jesus is not because he IS God Most High! My Bible’s study notes say that Jesus is telling the Jews that if elohyim is used for earthy rulers or judges, then it can be used even more so for him who is God Most High: Jesus the Messiah.
I hope that is helpful. God bless you!
