Before Thee let my cry come near,
O Lord; true to Thy word, teach me.
Before Thee let my pleading come;
True to Thy promise rescue me.
Since Thou Thy statutes teachest me,
O let my lips Thy praise confess.
Yea, of Thy word my tongue would sing,
For Thy commands are righteousness.
Be ready with Thy hand to help,
Because Thy precepts are my choice.
I’ve longed for Thy salvation, LORD,
And in Thy holy law rejoice.
O let Thine ordinances help;
My soul shall live and praise Thee yet.
A straying sheep, Thy servant, seek,
For Thy commands I ne’er forget.
