The Lord Our Righteousness (Jehovah Tsidkenu)

In his days Judah will be saved, and Israel will dwell securely. And this is the name by which he will be called: 'The LORD is our righteousness.'
Jeremiah 23:6 

I once was a stranger to grace and to God,
I knew not my danger; and felt not my load;
Though friends spoke in rapture of Christ on the tree,
Jehovah Tsidkenu was nothing to me.

I oft read with pleasure, to soothe or engage,
Isaiah’s wild measure and John’s simple page;
But even when they pictured the blood-sprinkled tree,
Jehovah Tsidkenu seemed nothing to me.

Like tears from the daughters of Zion that roll,
I wept when the waters went over His soul,
Yet thought not that my sins had nailed to the tree
Jehovah Tsidkenu — ’twas nothing to me.

When free grace awoke me by light from on high,
Then legal fears shook me, I trembled to die;
No refuge, no safety in self could I see —
Jehovah Tsidkenu my Saviour must be.

My terrors all vanished before the sweet name;
My guilty fear banished, with boldness I came
To drink at the fountain, life-giving and free—
Jehovah Tsidkenu is all things to me.

Jehovah Tsidkenu! My treasure and boast,
Jehovah Tsidkenu! I ne’er can be lost;
In Thee shall I conquer by flood and by field—
My cable, my anchor, my breastplate and shield!

Even treading the valley; the shadow of death,
This “watchword” shall rally my faltering breath;
For when from life’s fever my God sets me free,
Jehovah Tsidkenu my death-song shall be.
