John 1:34

I saw. John speaks as an eyewitness (cf. 1 John 1:1).

Son of God. There is some textual evidence (cf. p. 146) for the reading “the Elect of God.” See on Luke 1:35; cf. on John 1:1-3, 14. In the OT (Ps. 2:7) and in the pseudepigraphal Book of (Enoch 105:2,) about the 1st century B.C., “Son [of God]” appears as a distinctly Messianic title. Only in the Gospel of John is Jesus reported as using the title of Himself (chs. 5:25; 10:36; 11:4). The Jews of Christ’s time clearly understood the title in its highest sense (see eh. 19:7). John’s objective in writing a Gospel was to provide convincing evidence that “Jesus is the Christ, the Son of God” (eh. 20:31).
