Very good benadam. Another scripture to consider. Psalm 22:1-31 I believe Jesus was reciting this Psalm while on the cross. In order for Yahweh to be anyone’s Yahweh that person must exist, be alive. Psalm 115:17 Also Psalm 22:10 , Isaiah 49:1 are scriptures that I believe are about Jesus. Yahweh was not the Yahweh of Jesus before he existed only afterwards. Psalm 71:6 is not speaking of David . This dark saying is a frequent occurrence in David’s Psalms. Psalm 49:4 David used music to express spiritual things to the church but hide them from the world. Just as Jesus spoke in parables.
