They had remarked upon Him already, as being over lenient. Of Him indeed it had been prophesied, Ride on because of the word of truth, of meekness, and of righteousness. (Ps. 44) So as a teacher He exhibited truth, as a deliverer meekness, as a judge righteousness. When He spoke, His truth was acknowledged; when against His enemies He used no violence, His meekness was praised. So they raised the scandal on the score of justice. For they said among themselves, If He decide to let her go, He will not do justice; for the law cannot command what is unjust: Now Moses in the law commanded us, that such should be stoned: but to maintain His meekness, which has made Him already so acceptable to the people, He must decide to let her go. Wherefore they demand His opinion: And what sayest Thou? hoping to find an occasion to accuse Him, as a transgressor of the law: And this they said tempting Him, that they might have to accuse Him. But our Lord in His answer both maintained His justice, and departed not from meekness. Jesus stooped down, and with His finger wrote on the ground.
