The New John Gill Exposition of the Entire BibleMatthew 14:31
And immediately Jesus stretched forth his hand…
Syriac reads it, (htevrbw) , "and in that very moment"; for his case
requires immediate assistance, and Christ readily gave it; he
reached out his hand at once, being just by him,
and caught him;
as he was sinking to the bottom, and lifted him
up, and set him on his feet upon the water, and enabled him to walk
with him to the ship; but not without reproving him for the weakness
of his faith,
and said unto him, O thou of little faith:
he does not say, O thou
unbeliever! or, O thou who hast no faith! for some faith he had,
though but small; of this phrase, (See Gill on 6:30).
Wherefore didst thou doubt?
waver, fluctuate, or wast divided
between faith and fear. He was worthy of reproof, since he had had
the order of Christ to come to him upon the water; and an experience
of his power in supporting him thus far; and was now so near unto
him, that he had no room to doubt, whether it was he or not, nor of
his power to preserve him.
