Yalkut HaMakiri Tehilim (118 28): Tehlim (51:7) Behold I was born in sin. One view is that Dovid’s mother was the son of a beloved wife while another says a hated wife.. Yishai was separated from his wife for three years. After three years he had a pretty maid servant that he lusted for. He said to the slave,”My daughter; I prepared myself for you tonight to free you.” The slave went to his wife, “ “Save yourself and the soul of your husband from Hell.”She replied, “What is happening?”The slave told her everything. She replied, “My daughter what can I do since he hasn’t touched me for three years?. Go prepare yourself and so will I” And she did. That evening, the slave got up and extinguished the candle. and closed the door. The wife entered and the slave left. The wife was with her husband the whole night and became pregnant with Dovid. Because of his strong passion for the slave Dovid was born very ruddy compared to his brothers. His brothers wanted to kill him seeing that he was red {a sign of adultery]. However their father told them to leave him alone so instead of killing him they treated him instead as a slave and shepherd.
