"I have become a stranger to my brothers,
an alien to my mother’s sons.
For zeal for your house has consumed me,
and the reproaches of those who reproach you have fallen on me."
(also treated as Messianic in Romans 15:3

Since John is the one who is quoting and alluding to Psalm 69 so much:
John 2:17


John 15:25


John 19:28-29


In addition, the context of John 7:3-5












In church history, some people began to make unreasonable deductions about Mary, going beyond Scripture, adding to Scripture, and contradicting Scripture.
These unreasonable deductions led to the whole series of unbiblical traditions about Mary (prayers to her, IC, BA, co-mediatrix, some even calling for co-redemptrix to be defined as dogma) and led to the over-exalting of Mary, the over-emphasis on virginity (even after marriage), and celibacy as a requirement for all ministers in the RCC in church history. It is called a “higher way of holiness”. This implies that married folks cannot attain to a holy life, and it seems to exalt works over grace and faith.
Obviously, Psalm 69:5









By the way, a great sermon on Psalm 69 and emotions, including other quotes in Romans 11 and Acts 1, in his series on some of the Psalms in "Thinking and Feeling with God" by John Piper is here.
The apostle John seems to want us to get the connection by looking at Psalm 69 and all the other quotes in his gospel. (and Acts 1 and Romans 11 and 15)
Moreover, "for" in Psalm 69:9






John 7:3-9

So his brothers said to him, "Leave here and go to Judea, that your disciples also may see the works you are doing. For no one works in secret if he seeks to be known openly. If you do these things, show yourself to the world." For not even his brothers believed in him. Jesus said to them, "My time has not yet come, but your time is always here. The world cannot hate you, but it hates me because I testify about it that its works are evil. You go up to the feast. I am not going up to this feast, for my time has not yet fully come." After saying this, he remained in Galilee.
One of the ways skeptics attack the resurrection is they say Jesus only appeared in His resurrection to His friends, believers, disciples.
Well, Jesus' brothers were not believing in Him, and so, they were His enemies in this sense, even hating Him, implied here; because they wanted Him to show Himself to the world; and it says the Jews were seeking to kill Him. (John 7:1

They were His enemies in their unbelief; but they believed at the resurrection and afterward; especially, James (I Cor. 15:7



So Christ appeared to some enemies, namely His brothers, and Saul, who became Paul.
A powerful apologetic for the resurrection.
Seems clear that John and Jesus are making this connection between the sufferings of David in Psalm 69, that his own brothers, "my mother's sons are against me"; and also this is prophesied about the Messiah and it happen that way; and so it is clearly implied and alluded to by the way John uses Psalm 69, the connection "for" in verse 9, and the contrast between the faith of the disciples and lack of faith in His brothers in John 2:12-22

Putting it all together, it makes perfect sense why Jesus committed His mother to John, and seeing the connection of John 19 with Psalm 69 and the other gospels and giving His mother to John; (Psalm 69:21






So, the virgin birth of Christ is protected, by Scripture alone; Matthew 1:18-25

It is a man-made tradition.
