Anne Locke’s paraphrase of Psalm 51 breaks out into theology. The wisdom she has takes the scales off her eyes, and she sees her self justification as compounding the evil she has done. The text is

Behold, You desire truth in the [f]innermost being,
And in the hidden part You will make me know wisdom.

Psalm 51:6, NASB.

A visor masked the face of a knight, for his protection. Locke, correctly, says we must take our masks down, though they be armour.

Thou louest simple sooth, not hidden face
With trutheles visour of deceiuing showe.
Lo simplie, Lord, I do confesse my case,
And simplie craue thy mercy in my woe.
This secrete wisedom hast thou graunted me,
To se my sinnes, & whence my sinnes do growe:
This hidden knowledge haue I learnd of thee,
To fele my sinnes, and howe my sinnes do flowe
With such excesse, that with vnfained hert,
Dreding to drowne, my Lorde, lo howe I flee,
Simply with teares bewailyng my desert,
Releued simply by thy hand to be.
Thou louest truth, thou taughtest me the same.
Helpe, Lord of truth, for glory of thy name.
