Psalms 119:131

I opened my mouth, and panted - A metaphor taken from an animal exhausted in the chase. He runs, open-mouthed, to take in the cooling air; the heart beating high, and the muscular force nearly expended through fatigue. The psalmist sought for salvation, as he would run from a ferocious beast for his life. Nothing can show his earnestness in a stronger point of view.

I opened my mouth and panted - All this is the language of deep emotion. We breathe hard under the influence of such emotion; we open the mouth wide, and pant, as the ordinary passage for the air through the nostrils is not sufficient to meet the needs of the lungs in their increased action. The idea is, that his heart was full; that he had such an intense desire as to produce deep and rapid breathing; that he was like one who was exhausted, and who "panted" for breath. Compare the notes at Psalm 42:1.

For I longed for thy commandments - The word here rendered "longed" occurs nowhere else. It means to desire earnestly. See the notes at Psalm 119:20.

119:131 Panted - I thirst after thy precepts, and pursue them eagerly.
