Deal with thy servant according unto thy mercy - Not according to justice - for, sinners as we are, we can never urge that as a plea before God. No man who knows himself could ask of God to deal with him according to the strict and stern principles of justice. But we may ask him to deal with us according to mercy - for mercy is our only plea, and the mercy of God - vast and boundless - constitutes such a ground of appeal as we need. No man can have any other; no man need desire any other.
And teach me thy statutes - See the notes at Psalms 119:12. Show thy mercy to me in teaching me thy law.
