God answers Abimelech in Genesis 20:6, and the Targum's rendering is extraordinary.
"And the Word of the Lord said to him in a dream, Before Me also it is manifest that in the truthfulness of thy heart thou didst this, and so restrained I thee from sinning before Me; therefore I would not permit thee to come near her."
God affirms everything Abimelech has said. The king's heart was sincere. The king's hands were clean. And then the Targum offers a stunning theological detail: the reason Abimelech did not touch Sarah was not because he chose not to. It was because God had actively prevented him. Restrained I thee from sinning before Me. The Aramaic verb — mena'ti yat'ach — means "I held you back."
The rabbis of the Talmud (Bava Kamma 92a) read this verse as evidence of a principle they called siyata di-shmaya — the help of Heaven. Sometimes, when a person's heart is genuinely pure, God actively intervenes to prevent them from stumbling into sins that would harm them. Not because the person is perfect. Because the person is trying.
This is one of the most tender doctrines in rabbinic theology. Free will is real. Responsibility is real. And yet — quietly, invisibly — the Holy One sometimes slips between a sincere person and a disaster they did not see coming, and holds the disaster back with His own Word.
Abimelech did not know he was being helped. He only discovered it in the dream, afterward, when God explained.
The takeaway: some of the sins you did not commit were prevented by a hand you will never see in this lifetime.
