'Strong' in the Bible

The Lord is good, a strong place in the day of trouble; and he has knowledge of those who take him for their safe cover.

A crusher has come up before your face: keep a good look-out, let the way be watched, make yourself strong, let your power be greatly increased.

Get water for the time when you are shut in, make strong your towns: go into the potter's earth, stamping it down with your feet, make strong the brickworks.

Sorrow! how are the keepers of your flock sleeping, O king of Assyria! your strong men are at rest; your people are wandering on the mountains, and there is no one to get them together.
