Charles H. Spurgeon on Psalms 119:131

I opened my mouth, and panted. So animated was his desire that he looked into the animal world to find a picture of it. He was filled with an intense longing, and was not ashamed to describe it by a most expressive, natural, and yet singular symbol. Like a stag that has been hunted in the chase, and is hard pressed, and therefore pants for breath, so did the Psalmist pant for the entrance of God's word into his soul. Nothing else could content him. All that the world could yield him left him still panting with open mouth.

For I longed for thy commandments. Longed to know them, longed to obey them, longed to be conformed to their spirit, longed to teach them to others. He was a servant of God, and his industrious mind longed to receive orders; he was a learner in the school of grace, and his eager spirit longed to be taught of the Lord.
