2 Chronicles 15:11 Meaning

9And he gathered all Judah and Benjamin, and the strangers with them out of Ephraim and Manasseh, and out of Simeon: for they fell to him out of Israel in abundance, when they saw that the LORD his God was with him.

10So they gathered themselves together at Jerusalem in the third month, in the fifteenth year of the reign of Asa.

11And they offered unto the LORD the same time, of the spoil which they had brought, seven hundred oxen and seven thousand sheep.

12And they entered into a covenant to seek the LORD God of their fathers with all their heart and with all their soul;

13That whosoever would not seek the LORD God of Israel should be put to death, whether small or great, whether man or woman.
