'Lose' in the Bible

No one shall suffer miscarriage or be barren in your land; I will fulfill the number of your days.

The sons of Dan said to him, “Do not let your voice [of complaint] be heard among us, or else angry men will assault you and you will lose your life, along with the lives of [everyone in] your household.”

Then Ahab said to Obadiah, “Go into the land to all the sources of water and to all the streams; perhaps we may find grass and keep the horses and mules alive, and not have to kill some of the cattle.”

A time to search and a time to give up as lost;A time to keep and a time to throw away.

A highway will be there, and a roadway;And it will be called the Holy Way.The unclean will not travel on it,But it will be for those who walk on the way [the redeemed];And fools will not wander on it.

Some of those who are [spiritually] wise and have insight will fall [as martyrs] in order to refine, to purge and to make those among God’s people pure, until the end time; because it is yet to come at the time appointed [by God].
