2 Chronicles 20:14-22

New International Version

¹⁴ Then the Spirit of the Lord came on Jahaziel son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a Levite and descendant of Asaph, as he stood in the assembly.

¹⁵ He said: “Listen, King Jehoshaphat and all who live in Judah and Jerusalem! This is what the Lord says to you: ‘Do not be afraid or discouraged because of this vast army. For the battle is not yours, but God’s. ¹⁶ Tomorrow march down against them. They will be climbing up by the Pass of Ziz, and you will find them at the end of the gorge in the Desert of Jeruel. ¹⁷ You will not have to fight this battle. Take up your positions; stand firm and see the deliverance the Lord will give you, Judah and Jerusalem. Do not be afraid; do not be discouraged. Go out to face them tomorrow, and the Lord will be with you.’”

¹⁸ Jehoshaphat bowed down with his face to the ground, and all the people of Judah and Jerusalem fell down in worship before the Lord.¹⁹ Then some Levites from the Kohathites and Korahites stood up and praised the Lord, the God of Israel, with a very loud voice.

²⁰ Early in the morning they left for the Desert of Tekoa. As they set out, Jehoshaphat stood and said, “Listen to me, Judah and people of Jerusalem! Have faith in the Lord your God and you will be upheld; have faith in his prophets and you will be successful.” ²¹ After consulting the people, Jehoshaphat appointed men to sing to the Lord and to praise him for the splendour of his^[a] holiness as they went out at the head of the army, saying:

²² As they began to sing and praise, the Lord set ambushes against the men of Ammon and Moab and Mount Seir who were invading Judah, and they were defeated.

I’ll go in the strength of the Lord
In paths He has marked for my feet;
I’ll follow the light of His word,
Nor shrink from the dangers I meet.
His presence my steps shall attend,
His fullness my wants shall supply;
On Him, till my journey shall end,
My unwavering faith shall rely.

Chorus
I’ll go (I’ll go,) I’ll go in the strength,
I’ll go in the strength of the Lord,
I’ll go, (I’ll go,) I’ll go in the strength,
I’ll go in the strength of the Lord.

I’ll go in the strength of the Lord
To work He appoints me to do;
In joy which his smile doth afford
My soul shall her vigour renew.
His wisdom shall guard me from harm,
His power my sufficiency prove;
I’ll trust His omnipotent arm,
And prove His unchangeable love.

I’ll go in the strength of the Lord
To conflicts which faith will require,
His grace as my shield and reward,
My courage and zeal shall inspire.
Since he gives the word of command,
To meet and encounter the foe,
With his sword of truth in my hand,
To suffer and triumph I’ll go.
