And it was the sabbath day when Jesus made the clay, and opened his eyes.

Now the day on which Jesus made the clay and opened the man's eyes was the Sabbath.

Now the day on which the earth was mixed by Jesus and the man's eyes were made open was the Sabbath.

Now it was a Sabbath when Jesus made the clay and gave him his sight.

Now it was the Sabbath. Christ purposely selected the Sabbath-day, which must have given ground of offense to the Jews. He had already found, in the case of the paralytic, that this work was liable to slander. Why then does he not avoid the offense -- which he could easily have done -- but because the defense malignantly undertaken by men would tend to magnify the power of God? The Sabbath-day serves as a whetstone to sharpen them, to inquire more eagerly into the whole matter. And yet what advantage do they reap from a careful and earnest examination of the question but this, that the truth of the Gospel shines more brightly? We are taught by this example that, if we would follow Christ, we must excite the wrath of the enemies of the Gospel; and that they who endeavor to effect a compromise between the world and Christ, so as to condemn every kind of offenses, are altogether mad, since Christ, on the contrary, knowingly and deliberately provoked wicked men. We ought to attend, therefore, to the rule which he lays down, that they who are blind, and leaders of the blind, (Matthew 15:14,) ought to be disregarded.

It was the Sabbath - Some of the ancient rabbins taught, and they have been followed by some moderns, not much better skilled in physic than themselves, that the saliva is a cure for several disorders of the eyes; but the former held this to be contrary to the law, if applied on the Sabbath. See Lightfoot's Hor. Talm.

And it was the sabbath day when Jesus made the clay,.... Which was reckoned a violation of the sabbath, John 9:16, and was one reason why they had the man to the Pharisees to be examined, and why they were desirous of knowing where Jesus was:
and opened his eyes; by putting on the clay, and sending him to wash in the Pool of Siloam: nor did the miracle, nor the good done to the man, excuse with them, what they thought a breach of the sabbath.

It was the sabbath day. Saturday, the Jewish Sabbath. We have found in the case of the miracle at the pool of Bethesda how they were angered by any apparent violation of the day.

Anointing the eyes - With any kind of medicine on the Sabbath, was particularly forbidden by the tradition of the elders.
