God warned the unjust judges that they themselves would suffer judgment for their injustice. God had appointed them as "gods" (i.e, individuals with power by God"s authority). He had made them His sons in the sense of His representatives on earth (cf. 2 Samuel 7:14). Nevertheless because they had not behaved as God, who judges justly, they would die as mere men without honor as God"s sons. They would die as all the other Israelites would. "Men" and "rulers" ( Psalm 82:7) is a merism that signifies all mortals. [1][source]
Jesus" accusers charged Him with blasphemy when He claimed to be the Son of God ( John 10:33). In replying to their accusation, Jesus quoted Psalm 82:6 to remind them that God called Israel"s judges His sons. His point was that it was not inappropriate for Him to call Himself the Son of God. Jesus, of course, is God"s ultimate Judge of all humankind, so it was especially appropriate for Him to call Himself the Son of God. [source][source][source]
