Psalms8:2 is quoted in Matthew21:6.
2 Out of the mouth of children and sucklings you have founded strength, On account of those showing hostility to you, So as to make the enemy and the one taking his vengeance desist. (Psalm8).
15 When the chief priests and the scribes saw the marvellous things he did and the boys that were crying out in the temple and saying: Save, we pray, the Son of David! they became indignant
16 and said to him: Do you hear what these are saying? Jesus said to them: Yes. Did you never read this, 'Out of the mouth of babes and sucklings you have furnished praise'? (Matthew21).
Here is the whole Psalm and it's symbolic interpretation applying today...
1 Oh Jehovah our Lord, how majestic your name is in all the earth [true religious administration of TCC4], You whose dignity is recounted above the heavens! [the physical heavens, sky. It is praised also in the angelic realm]
2 Out of the mouth of children [newly baptized who just joined the church] and sucklings [bible students thinking about joining, just learning the basic truths of the deeper meanings of the Bible] you have founded strength [doctrinal strenght of the church. In our experience, the Holy Spirit takes delight in distributing deep understandings and spiritual gems to those newly acquainted with TCC4], On account of those showing hostility to you, So as to make the enemy and the one taking his vengeance desist. [FDS4 cannot be slandered by enemies to claim exclusivness in Bible interpretation and understandings.]
3 When I see your heaven/sky, the works of your fingers [not hand!], The moon and the stars that you have prepared/established [this must be literal, since God did not establish Satan?],
4 What is mortal man that you keep him in mind, And the son of earthling man/Adam that you take care of/deposit him? [maximally distributive, twofold Reader Question with 2 answers.][1. Mortal man is still dust, unsanctified but remembered by God for a resurrection into the Kingdom. 2. Sons of the last Adam are the saints, now streaming to God's mountain. Jehovah takes care of their spirit by giving them an everlasting angelic vehicle]
5 And you made him lacking a little from godlike ones/elohim [we are the brothers of the angels but our human bodies lack the power and mental capability of the angels], And with glory and splendor you then crowned him. [Giving man the crown of life to rule with Jesus][Humans who overcome and are sealed will judge the angels]
6 You make him dominate over the works of your hands [first earthly and then heavenly] [the temple of true worship]; Everything you have put under his foot [The first Adam ruled over all physical creation, the last Adam and his wife rule over the entire creation] [sons of Jacob, sons of Isaac, sons of Abraham]:
7 Sheep [mild teachers and counsellors] and cattle [preparing the field, researchers], all of them, And also the beasts of the field [evangelizer],
8 The birds of heaven [the saints] and the fish of the sea/increase of the west, passing through the paths of the seas/the passover caravan. [the water baptized who passed through the sea of the flood?]
9 Oh Jehovah our Lord, how majestic your name is in all the earth!(Psalms8).
