'Test' in the Bible

“Please test your servants for 10 days. Let us be given vegetables to eat and water to drink.

So he gave ear to them in this thing and put them to the test for ten days.

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].
