Okay, you are saying it pertains to Jesus then??
Psalm 69:5
O God, Thou knowest my foolishness, and my sins are not hid from Thee.
So Jesus would never say “my sins are not hid from Thee” because Jesus simply did not Sin.
Since all of Psalm 69 is a first person narrative; it means that we are now saying 69:8 is about Jesus but the whole Psalm is in the first person.
“8 I am a foreigner to my own family,
a stranger to my own mother’s children;”
Same person speaks in 69:8 who speaks in verse 69:5.
