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.

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,.... As a person out of breath does, through walking or running; he stops and pants, and opens his mouth, to draw in air to his relief: or as hungry and thirsty persons pant for food and drink, and open their mouths to receive it, before it can well be brought to them. So the psalmist panted after God, and communion with him; desired the sincere milk of the word; longed for the breasts of ordinances, and even fainted for the courts of the Lord, Psalm 42:1;

for I longed for thy commandments; for an opportunity of waiting upon God in the way of his duty; to hear his word, and attend his worship.

I opened my mouth, and {c} panted: for I longed for thy commandments.

(c) My zeal toward your word was so great.

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

131-135. An ardent desire (compare Ps 56:1, 2) for spiritual enlightening, establishment in a right course, deliverance from the wicked, and evidence of God's favor is expressed

I opened my mouth, and panted-as a traveller in a hot desert pants for the cooling breeze (Ps 63:1; 84:2).

119:129-136 The wonders of redeeming love will fix the heart in adoration of them. The Scriptures show us what we were, what we are, and what we shall be. They show us the mercy and the justice of the Lord, the joys of heaven, and the pains of hell. Thus they give to the simple, in a few days, understanding of those matters, which philosophers for ages sought in vain. The believer, wearied with the cares of life and his conflicts with sin, pants for the consolations conveyed to him by means of the sacred word. And every one may pray, Look thou upon me, and be merciful unto me as thou usest to do unto those that love thy name. We must beg that the Holy Spirit would order our steps. The dominion of sin is to be dreaded and prayed against by every one. The oppression of men is often more than flesh and blood can bear; and He who knoweth our frame, will not refuse to remove it in answer to the prayers of his people. Whatever obscurity may appear as to the faith of the Old Testament believers, their confidence at the throne of grace can only be explained by their having obtained more distinct views of gospel privileges, through the sacrifices and services of their law, than is generally imagined. Go to the same place, plead the name and merits of Jesus, and you will not, you cannot plead in vain. Commonly, where there is a gracious heart, there is a weeping eye. Accept, O Lord, the tears our blessed Redeemer shed in the days of his flesh, for us who should weep for our brethren or ourselves.
