English Standard Version Hebrews 7:7
It is beyond dispute that the inferior is blessed by the superior.
So the higher blesses the lower.
English Standard Version Psalm 135:20
O house of Levi, bless the LORD! You who fear the LORD, bless the LORD!
Now we have the lower blesses the higher. What is the meaning of this?
Genesis 14:18 And Melchizedek king of Salem brought out bread and wine. (He was priest of God Most High.) 19And he blessed him and said,
“Blessed be Abram by God Most High, Possessorb of heaven and earth; 20and blessed be God Most High, who has delivered your enemies into your hand!”
Melchizedek blessed Abram. God blessed Abram. Then, God was blessed.
