Proof Satan needed to know if Jesus was the son of god ~ Cross reference of Matthew 4:6 to Psalm 91:11

If you read Matthew 4, Satan tempts Jesus 3 times,  you will see that 2 times Matthew quotes the right passages from Tanakh in context but for this one he uses a Psalm of David out of context. 

Psalm 91 is such a beautiful and reassuring Psalm which all of us use when we are headed out to do things that are challenging and uncertain. 

What I also found strange is that Satan would be convinced if Jesus was saved by angels when he jumps of the temple top that he is indeed the son of god.

I can understand the value of a stone becoming bread and a Jew not worshipping anyone / anything but the ONE TRUE G-d of the universe but this jumping down 30 feet and being saved by angels was a bit odd.

This post is not intended to offend anyone's faith but for those people who are Seeking the truth of THE ONE TRUE G-D of the universe to who we owe all our love, gratitude & devotion.

My encouragement to you is that you read the whole chapter of Tanakh that the Greek text quotes so you get the context and understand what G-d actually said.

G-d Bless and Seek THE Truth.

Matthew 4:6 “If you are the Son of God,” he said, “throw yourself down. For it is written: “‘He will command his angels concerning you, and they will lift you up in their hands, so that you will not strike your foot against a stone.’[c]”

Psalm 91:11 For He will command His angels on your behalf to guard you in all your ways. 12 On [their] hands they will bear you, lest your foot stumble on a stone.

Consider the below points that I raise to see if Psalm 91 was given to us by David to tell this is how Satan will know that Jesus is the son of god.

1. This is such a beautiful Psalm of David where he says how G-d will protect him from harm. We all pray this Psalm and as children of G-d who need G-d’s protection we need to do this daily.
2. It conveys that those who look to G-d will get help when in trouble just like David did.
3. G-d does many miracles in each of our lives where his protection saves us from harm and at times from death. When I look back at my life I can witness that G-d saved me from harm and even a few times from death. I get shivers when I think about those incidents and know that G-d saved my life.
4. Would angels coming and picking up Jesus after he jumped have proved that he is the son of god? 
5. Most of the things in Psalm 91:15 did not happen with Jesus, he was crucified by Romans.
6. The below verse is a problem for trinitarians. Why would god honor god and why would god give long life to god?

Psalm 91:15 He will call Me, and I shall answer him; I am with him in distress; I shall rescue him and I shall honor him. 16 With length of days I shall satiate him, and I shall show him My salvation.
