'Prevented' in the Bible

Onan knew that the child (heir) would not be his [but his dead brother’s]; so whenever he lay with his brother’s widow, he spilled his seed on the ground [to prevent conception], so that he would not give a child to his brother.

Those men said to Moses, “We are [ceremonially] unclean because of [touching] a dead body. Why are we being restrained from presenting the Lord’s offering at its appointed time among the Israelites?”

So now, my lord, as the Lord lives, and as your soul lives, since the Lord has prevented you from shedding blood, and from avenging yourself by your own hand, now then let your enemies and those who seek to do evil to my lord, be as [self-destructive as] Nabal.

Nevertheless, as the Lord the God of Israel lives, who has prevented me from harming you, if you had not come quickly to meet me, most certainly by the morning light there would not have been left to Nabal so much as one male.”
