John Gill Commentary John 11:10

"But if a man walk in the night, he stumbleth, because the light is not in him." — John 11:10 (ASV)

But if a man walk in the night
After the sun is set, and there is no light in the air and heavens to direct him:

he stumbles ;
at everything that lies in the way,

because there is no light in him ;
there being none from above communicated to him. So our Lord suggests, that when the time of his death was come, he would then fall a prey into the hands of his enemies, but till then he would walk safe and secure; and he had nothing to fear from them, and therefore could go into Judea again, with intrepidity and unconcern.
