A.T. Robertson Commentary John 6:37

"All that which the Father giveth me shall come unto me; and him that cometh to me I will in no wise cast out." — John 6:37 (ASV)

All that (παν ο). Collective use of the neuter singular, classic idiom, seen also in 6:39; 17:2,24; 1 John 5:4. Perhaps the notion of unity like εν in 17:21 underlies this use of παν ο.

Giveth me (διδωσιν μο). For the idea that the disciples are given to the Son see also 6:39,65; 10:29; 17:2,6,9,12,24; 18:9.

I will in no wise cast out (ου μη εκβαλω εξω). Strong double negation as in verse 35 with second aorist active subjunctive of βαλλω. Definite promise of Jesus to welcome the one who comes.
