("My son, My male-firstborn, is Israel." — Shᵊm•otꞋ 4.22)
Ta•na"khꞋ refers or alludes to a son of ël•oh•imꞋ about 14 times; every one of which refers explicitly to Yi•sᵊr•â•eilꞋ or Yi•sᵊr•â•eilꞋ as represented by her MëlꞋëkh ha-Mâ•shiꞋakh (anointed king). Ta•na"khꞋ never permits any divine "Son" — which is the fulfillment of Dân•iy•eilꞋ 7.25!
The only basis for the Christian doctrine of a divine "Son of God" is in the 4th century C.E. product of gentile Hellenist (i.e., idolatrous) Roman Christian Διαθηκη Καινη (NT), whose authenticity and legitimacy — the earliest extant Christian historian, Eusebius, documented — was denied and refused by the original, 1st century Nᵊtzâr•imꞋ Jews who followed RibꞋi Yᵊho•shuꞋa and accepted only "their own Hebrew Ma•titᵊyâhꞋu" (NHM) as a legitimate account of the life and teachings of RibꞋi Yᵊho•shuꞋa.
