But when he saw the wind boisterous
 Or "strong", blowing hard against him, and raising up the waves, which beat with great violence upon him, 
 he was afraid;
 though Christ was so nigh him, and he had had such an instance of his power in bearing him up, causing him to walk upon the waters thus far; which shows, that his faith was imperfect: 
 and beginning to sink;
 through fear, and the violence of the wind and waves, just ready to be immersed, and go down to the bottom of the sea, 
 he cried;
 being in a great fright and much danger, and with great importunity and eagerness, 
 saying, Lord, save me:
 I am just going, I shall certainly perish else; still having so much faith in Christ, that he was able to save him in the last extremity.
