King James Dictionary

Bethink "Lay it to heart"; consider and repent. If they sin against thee, (for there is no man which sinneth not,) and thou be angry with them, and deliver them over before their enemies, and they carry them away captives unto a land far off or near; yet if they BETHINK themselves in the land whither they are carried captive, and turn and pray unto thee in the land of their captivity, saying, We have sinned, we have done amiss, and have dealt wickedly...then hear thou from the heavens, even from thy dwelling place, their prayer and their supplications, and maintain their cause, and forgive thy people which have sinned against thee.
