Mark 8:23

Led him out of the town - Why this was done the sacred writers have not told us. It might have been to avoid the collecting of a multitude, and thus to have escaped the designs of the Pharisees who were attempting to take his life, and chiefly on a charge of sedition and of exciting the people. On this account Jesus chose to perform the miracle alone, thus showing that while he did good, he desired to do it in such a way as to avoid the “appearance” of evil, and to prevent, at the same time, ostentation and the malice of his enemies.

Spit on his eyes - Why this was done is not known. It was evidently not intended to perform the cure by any natural effect of the spittle. It was to the man a “sign,” an evidence that it was the power of Jesus. The eyes were probably closed. They were perhaps “gummed” or united together by a secretion that had become hard. To apply spittle to them - to wet them - would be a “sign,” a natural expression of removing the obstruction and opening them. The power was not in the spittle, but it attended the application of it.

Saw aught - Saw anything.
