Theophylact of Bulgaria
From this, we also understand the importance of not seeking recognition when we do good deeds, as Jesus Himself instructed those He healed to remain silent about Him. He was aware that they might choose to disobey and share their experiences, but, as I mentioned, He teaches us to avoid prideful vanity by advising them to keep it to themselves. Christ directs him to the priest since, according to the law, a leper could only reenter the city after the priest confirmed his healing from leprosy; otherwise, he would be cast out (Leviticus 13:46). Alongside this, the Lord instructed him to offer a gift, as was customary for those who had been purified (Leviticus 14). This demonstrates that He was not in opposition to the law; rather, He held it in such high regard that He required its commands to be observed.
