Charles Spurgeon Commentary John 7:5-6

"For even his brethren did not believe on him. Jesus therefore saith unto them, My time is not yet come; but your time is always ready." — John 7:5-6 (ASV)

Now Moses in the law commanded us, that such should be stoned: but what sayest thou? This they said, tempting him, that they might have to accuse him.

They could accuse him either way. If he sanctioned their stoning the woman, they would charge him with violating the Roman law; but if he said that she should not be stoned, then they would say that he differed from Moses and set aside the law of God.
