Chronicles II 15:2

2 and he went out to meet Asa, and all Juda and Benjamin, and said, Hear me, Asa, and all Juda and Benjamin. The Lord with you, while ye are with him; and if ye seek him out, he will be found of you; but if ye forsake him, he will forsake you.

Chronicles II 15:2 Meaning and Commentary

2 Chronicles 15:2

And he went out to meet Asa
From Jerusalem, as Asa was coming to it:

and said unto him, hear ye me, Asa, and all Judah and Benjamin;
the principal inhabitants of which tribes had been collected, and went to this war, and were now returning:

the Lord is with you, while ye be with him;
it was a clear case he had been with them, in giving them the victory over the Ethiopians; and as long as they continued in the service of God, and abode by his pure worship, they might expect he would yet be with them, otherwise not:

and if ye seek him, he will be found of you;
you will see his face, and enjoy his favour, and have his presence, and help from him in every time of need, when they sought him by prayer and supplication, as Asa had, and attended his worship and ordinances:

but if ye forsake him;
his laws and his service:

he will forsake you;
and leave you to fall into the hands of your enemies.

Chronicles II 15:2 In-Context

1 And Azarias the son of Oded—upon him came the Spirit of the Lord,
2 and he went out to meet Asa, and all Juda and Benjamin, and said, Hear me, Asa, and all Juda and Benjamin. The Lord with you, while ye are with him; and if ye seek him out, he will be found of you; but if ye forsake him, he will forsake you.
3 And Israel a long time without the true God, and without a priest to expound , and without the law.
4 But he shall turn them to the Lord God of Israel, and he will be found of them.
5 And in that time there is no peace to one going out, or to one coming in, for the terror of the Lord is upon all that inhabit the lands.
