Charles H. Spurgeon on Psalms 119:135

Make thy face to shine upon thy servant. Oppressors frown, but do thou smile. They darken my life, but do thou shine upon me, and all will be bright. The Psalmist again declares that he is God's servant, and he seeks for no favour from others, but only from his own Lord and Master.

And teach me thy statutes. This is the favour which he considers to be the shining of the face of God upon him. If the Lord will be exceeding gracious, and make him his favourite, he will ask no higher blessing than still to be taught the royal statutes. See how he craves after holiness; this is the choicest of all gems in his esteem. As we say among men that a good education is a great fortune, so to be taught of the Lord is a gift of special grace. The most favoured believer needs teaching; even when he walks in the light of God's countenance he has still to be taught the divine statutes or he will transgress.
