Matthew 1:17 speaks of the 14 generations from Abraham to David, and 14 generations from David to the Babylonian exile, and 14 generations from the Babylonian exile to Jesus.
The 14th letter of the Hebrew alphabet is symbolic of the Messiah according to this Jewish website.
According to this Hebrew/Christian website the letter Nun also represents the word
‘faithfulness’, and in Aramaic, the word for ‘fish’.
This website has an interesting commentary of the letter Nun that is found to be inverted at the beginning and at the end of Hebrew text of Numbers 10:35-36 (which speaks of the the ark of covenant).
Psalm 145 is an acrostic Psalm that is missing the 14th verse representing the 14th letter of the Hebrew alphabet which as previously stated is the letter Nun. This verse is found in the Septuagint version and in the Dead Sea Scrolls: “Faithful (neamen) is YHWH in all his ways, and merciful in all his works.” Wikipedia gives an explanation as to why this verse is not found in the Masoretic text.
Finally, Ps.145:14 is quoted in one early church writing as representing Jesus Christ:
All we of the faithful, therefore, who are the disciples of Christ, believe His promises. For He that has promised it cannot lie; as says the blessed prophet David: “The Lord is faithful in all His words, and holy in all His works.” For He that framed for Himself a body out of a virgin, is also the Former of other men. And He that raised Himself from the dead, will also raise again all that are laid down. He who raises wheat out of the ground with many stalks from one grain, He who makes the tree that is cut down send forth fresh branches, He that made Aaron’s dry rod put forth buds, will raise us up in glory; He that raised him up that had the palsy whole, and healed him that had the withered hand, He that supplied a defective part to him that was born blind from clay and spittle, will raise us up; He that satisfied five thousand men with five loaves and two fishes, and caused a remainder of twelve baskets, and out of water made wine, and sent a piece of money out of a fish’s mouth by me Peter to those that demanded tribute, will raise the dead. For we testify all these things concerning Him, and the prophets testify the other. We who have eaten and drunk with Him, and have been spectators of His wonderful works, and of His life, and of His conduct, and of His words, and of His sufferings, and of His death, and of His resurrection from the dead, and who associated with Him forty days after His resurrection, Acts 1:3 and who received a command from Him to preach the Gospel to all the world, and to make disciples of all nations, Matthew 28:19 and to baptize them into His death by the authority of the God of the universe, who is His Father, and by the testimony of the Spirit, who is His Comforter,— we teach you all these things which He appointed us by His constitutions, before “He was received up in our sight into heaven,” Acts 1:9 to Him that sent Him. And if you will believe, you shall be happy; but if you will not believe, we shall be found innocent, and clear from your incredulity.
