I will sing of mercy and judgment: unto Thee, O Lord, will I sing.@Psalm 101:1
Isaac Watts (1674–1748)

Isaac Watts, The Psalms of David 1719. The magistrate’s psalm.

Queen’s Cross Kenneth G. Finlay, in The Primitive Methodist Hymnal Supplement with Tunes, edited by George Booth (London: Primitive Methodist Publishing House, 1912), number 57 (🔊 pdf nwc).

Mercy and judgment are my song;
And since they both to Thee belong,
My gracious God, my righteous king,
To Thee my songs and vows I bring.

If I am raised to bear the sword,
I’ll take my counsels from Thy Word;
Thy justice and Thy heav’nly grace
Shall be the pattern of my ways.

Let wisdom all my actions guide
And let my God with me reside;
No wicked thing shall dwell with me,
Which may provoke Thy jealousy.

No sons of slander, rage, and strife
Shall be companions of my life;
The haughty look, the heart of pride
Within my doors shall ne’er abide.

I’ll search the land, and raise the just
To posts of honor, wealth, and trust:
The men that work Thy holy will
Shall be my friends and favorites still.

In vain shall sinners hope to rise
By flattering or malicious lies;
And while the innocent I guard,
The bold offender shan’t be spared.

The impious crew, that factious band,
Shall hide their heads or quit the land;
And all that break the public rest,
Where I have power shall be suppressed.
