'Hadn't' in the Bible

There was one man from Zorah, from the family of the descendants of Dan, whose name was Manoah. Since his wife was infertile, she hadn't borne children.

Then the men of the city answered him just before sunset on the seventh day: "What is sweeter than honey? What are stronger than lions?" Samson responded, "If you hadn't plowed with my heifer, you wouldn't have solved my riddle."

They discovered among the inhabitants of Jabesh-gilead 400 young virgins who hadn't had sex with a man, and they brought them to the encampment at Shiloh in the territory of Canaan.
