An Exposition on Psalm 119:57-61, by Charles Haddon Spurgeon. The following contains an excerpt from his work, "Treasury of David".

CHETH. Thou art my portion, O LORD: I have said that I would keep thy words. I intreated thy favour with my whole heart: be merciful unto me according to thy word. I thought on my ways, and turned my feet unto thy testimonies. I made haste, and delayed not to keep thy commandments. The bands of the wicked have robbed me: but I have not forgotten thy law. At midnight I will rise to give thanks unto thee because of thy righteous judgments. I am a companion of all them that fear thee, and of them that keep thy precepts. The earth, O LORD, is full of thy mercy: teach me thy statutes.
~ Psalm 119:57-64

The LORD is my portion, saith my soul; therefore will I hope in him.
~ Lamentations 3:24

I have sworn, and I will perform it, that I will keep thy righteous judgments.
~ Psalm 119:106

Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
~ Hebrews 10:22

With my whole heart have I sought thee: O let me not wander from thy commandments.
~ Psalm 119:10

In God I will praise his word, in God I have put my trust; I will not fear what flesh can do unto me.
~ Psalm 56:4

Let us search and try our ways, and turn again to the LORD.
~ Lamentations 3:40

And rend your heart, and not your garments, and turn unto the LORD your God: for he is gracious and merciful, slow to anger, and of great kindness, and repenteth him of the evil.
~ Joel 2:13

Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.
~ Ecclesiastes 9:10

To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:
~ Galatians 1:16

And as troops of robbers wait for a man, so the company of priests murder in the way by consent: for they commit lewdness.
~ Hosea 6:9

I have gone astray like a lost sheep; seek thy servant; for I do not forget thy commandments.
~ Psalm 119:176

Ver. 57. Thou art my portion, O LORD. A broken sentence. The translators have mended it by insertions, but perhaps it had been better to have left it alone, and then it would have appeared as an exclamation, "My portion, O Lord!" The poet is lost in wonder while he sees that the great and glorious God is all his own! Well might he be so, for there is no possession like Jehovah himself. The form of the sentence expresses joyous recognition and appropriation, "My portion, O Jehovah!" David had often seen the prey divided, and heard the victors shouting over it; here he rejoices as one who seizes his share of the spoil; he chooses the Lord to be his part of the treasure. Like the Levites, he took God to be his portion, and left other matters to those who coveted them. This is a large and lasting heritage, for it includes all, and more than all, and it outlasts all; and yet no man chooses it for himself until God has chosen and renewed him. Who that is truly wise could hesitate for a moment when the infinitely blessed God is set before him to be the object of his choice? David leaped at the opportunity, and grasped the priceless boon. Our author here dares exhibit the title deeds of his portion before the eye of the Lord himself, for he addresses his joyful utterance directly to God whom he boldly calls his own. With much else to choose from, for he was a king, and a man of great resources, Ire deliberately turns from all the treasures of the world, and declares that the Lord, even Jehovah, is his portion.

I have said that I would keep thy words. We cannot always look back with comfort upon what we have said, but in this instance David had spoken wisely and well. He had declared his choice: he preferred the word of God to the wealth of worldlings. It was his firm resolve to keep that is, treasure up and observe the words of his God, and as he had aforetime solemnly expressed it in the presence of the Lord himself, so here he confesses the binding obligation of his former vow. Jesus said, "If a man love me, he will keep my words, "and this is a case which he might have quoted as an illustration; for the Psalmist's love to God as his portion led to his keeping the words of God. David took God to be his Prince as well as his Portion. He was confident as to his interest in God, and therefore he was resolute in his obedience to him. Full assurance is a powerful source of holiness. The very words of God are to be stored up; for whether they relate to doctrine, promise, or precept, they are most precious. When the heart is determined to keep these words, and has registered its purpose in the court of heaven, it is prepared for all the temptations and trials that may befall it; for, with God as its heritage, it is always in good case.
