{Work not for} (m(8820)ergazesthe). Prohibition with m(885c) and
present middle imperative of ergazomai, old verb from ergon,
work. {The meat} (	(886e) br(9373)in). The act of eating ( Ro 14:17 ),
corrosion ( Mt 6:19 ), the thing eaten as here ( 2Co 9:10 ). See
on 浥oh 4:32|. {Which perisheth} (	(886e) apollumen(886e)). Present
middle participle of apollumi. They were already hungry again.
{Unto eternal life} (eis z(9388)n ai(936e)ion). Mystical metaphor quite
beyond this crowd hungry only for more loaves and fishes. Bernard
thinks that John has here put together various sayings of Christ
to make one discourse, a gratuitous interpretation. {Will give}
(d(9373)ei). Future active indicative of did(936d)i. The outcome is
still future and will be decided by their attitude towards the
Son of man (verse  51 ). {For him the Father, even God, hath
sealed} (	outon gar ho pat(8872) esphragisen ho theos). Literally,
"For this one the Father sealed, God." First aorist active
indicative of sphragiz(935c), to seal. See elsewhere in  Joh 3:33 
(attestation by man). Sealing by God is rare in N.T. ( 2Co 1:22  Eph 1:13  4:30 ). It is not clear to what item, if any single
one, John refers when the Father set his seal of approval on the
Son. It was done at his baptism when the Holy Spirit came upon
him and the Father spoke to him. Cf.  5:37 .
