Blessèd be the Lord my strength, who teacheth my hands to war, and my fingers to fight: My goodness, and my fortress; my high tower, and my deliverer; my shield, and He in whom I trust.@Psalm 144:1–2
Isaac Watts (1674–1748)

Isaac Watts, The Psalms of David 1719. Assistance and victory in the spiritual warfare.

Song 67 (Gibbons) Orlando Gibbons, 1623; arranged by Henry T. Smart (1813–1879) (🔊 pdf nwc).

Orlando Gibbons (1583–1625)

Forever blessèd be the Lord,
My Savior and my shield;
He sends His Spirit with His Word,
To arm me for the field.

When sin and hell their force unite,
He makes my soul His care,
Instructs me to the heav’nly fight,
And guards me through the war.

A friend and helper so divine
Does my weak courage raise;
He makes the glorious victory mine,
And His shall be the praise.
