So citing it the way you did was dishonest.
God is referred to by the 4 letter name and then Abraham is referred to as "my master" (adoni) as per Gen 23:6.
Actually, he text is not necessarily speaking of David, nor does it specifically say "prince" -- it says "nasi" which is a leader.
Psalm 45 never mentions Jesus, and it uses a different word (sarim) to indicate "generals" or "leaders" and it doesn't say anything about David's being demoted. Is. 32:1 also never mentions Jesus -- you read that in because you need to find it somewhere. The king and the sarim there have obvious referents who aren't Jesus.
Yes, God is referred to by the Tetragrammaton 4-letter name, but why would the other Lord be Abraham ? - Psalms 110:1
Agree, not specifically prince, but a leader as a chieftain would be in a ruling position, but Not as a king.
David is Not viewed as demoted - Ezekiel 34:24, but according to Christian text - Acts of the Apostles 2:34 - David is still 'asleep' in the grave.
Also, at Hebrews 11:13 Abraham died in faith but has Not received the promise.
Even the prophet Daniel looked forward to a future resurrection, or a future awakening from the grave - Daniel 12:2; Daniel 12:13
Because the one who will resurrect David, Abraham, and Daniel, etc. will be their ' life giver ' so in that sense then he will become their everlasting father ( life giver )- Isaiah 9:6
In Christian text there will be No earthly ruling king on earth but Jesus as King of Kings will govern over earth, so to be prince, leader, chieftain, etc. is a position of honor.
