Heart and spirit are put together so that we understand that David is asking God to clean him up from the inside.

The Holy Spirit and the Trinity (Part Four)
The Old Testament supplies the background to Jesus' use of "poor." From statements like David's, we realize that when God prophesies regarding Jesus—
The Spirit of the Lord GOD is upon Me, because the LORD has anointed Me to preach good tidings to the poor; He has sent Me to heal the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to those who are bound" (Isaiah 61:1)
—He is not speaking of the economically poor but those who are poor in spiritual qualities or poor in terms of a relationship with Him.
One can be spiritually poor regardless of how much money he possesses. He can be brokenhearted though living in grand houses, driving luxury automobiles, wearing the finest apparel, and circulating in the highest levels of society. Is being captive to sin and Satan or addicted to drugs, fashion, or the vain praise of men restricted by economic boundaries? Neither are godly attributes.
Jesus is not speaking to any clearly demarcated group. Though riches can motivate pride, the economically poor possess pride too. Jesus says the poor are blessed, but neither poverty nor wealth can confer spiritual blessings, though poverty may help to lead a person to humility. Both poverty and wealth can entail great spiritual peril. A poverty-stricken person can become very self-centered because of his desperate need, and a wealthy person can become equally self-centered through his profligacy. Jesus' words cover the whole span of mankind's circumstances because anyone without a right and true relationship with God can fall within His description. "Poor," as Jesus uses it, truly relates to a spiritual quality.
"Poor" does not stand alone; Jesus connects it with "spirit" to clarify His intention. Even as the economically poor are very aware of their need, so also are the poor in spirit. Yet a vast difference lies between this and being financially destitute. Poverty of spirit is a fruit not produced in the natural man, but a work of God's Holy Spirit in the minds of those He has called and is converting, explaining why being poor in spirit can span the whole economic spectrum. It is why an Abraham, Isaac, Jacob, David, or Joseph of Arimathea, all very wealthy men, can be simultaneously poor in spirit and materially blessed of God.
David referred to himself as a "poor" man, in need of what only God could supply. He perceived himself as destitute of the resources to improve his lot. He saw himself as beyond the help of men, afflicted, crushed, forsaken, desolate, miserable—as helpless spiritually as the poverty stricken are economically. Thus, recognizing his need, he cried out to God, and He heard him.
Another psalm by a thoroughly chastened and humbled David reveals in greater detail his recognition of the spiritual poverty in which he committed his sins. Notice the spiritual things David requested—things only God could supply—to fill his needs in Psalm 51:
Have mercy upon me . . . blot out my transgressions. Wash me thoroughly . . . cleanse me from my sin. . . . Make me to know wisdom. Purge me with hyssop. . . . Make me to hear joy and gladness. . . . Hide Your face from my sins. . . . Create in me a clean heart . . . renew a steadfast spirit within me. Do not cast me away from Your presence, and do not take Your Holy Spirit from me. Restore to me the joy of Your salvation, and uphold me with Your generous Spirit . . . . Deliver me from bloodguiltiness. . . . Open my lips and my mouth shall show forth Your praise. (verses 1-2, 6-12, 14-15)
To be poor in spirit is to acknowledge honestly and with understanding our spiritual poverty—indeed our spiritual bankruptcy—before God. We are sinners and on the strength of our lives deserve nothing but God's judgment. We have nothing to offer, nothing to plead, nothing with which to buy His favor. But upon profession of our faith coupled with repentance, He allows by His grace the blood of Jesus Christ, shed for the sins of the world, to cover our sins, justifying us and providing us with access into His presence.

The Beatitudes, Part Two: Poor in Spirit
When David saw the enormity of his sin, he realized he had hurt God and His purpose. His sorrow, chagrin, and remorse reached deeply into his heart, mind, and entire being. Our opposition to God should create a similar deep emotional response in us, for we have all played major roles in our Savior's death. He died for our sins. Emotional sorrow alone is not the answer, however. Paul says godly sorrow produces repentance (change) toward salvation, while worldly sorrow is like saying, "I'm sorry I got caught. I'll be more careful next time I sin."

Basic Doctrines: Repentance
David grasped the major difference between the hearts of God and humans. He uses the same Hebrew term for “create” as Moses uses in Genesis 1:1, when God created the heavens and the earth. Man's heart does not have the foundational goodness of our holy God's heart.
His primary request in the psalm concerns his sins of adultery with Bathsheba and the arranged murder of Uriah. He first craved forgiveness and cleansing of those sins, but he also undoubtedly wanted his heart to be created anew so that he would never repeat such sinful conduct. He desired the nature of his heart in pristine condition so he could truly glorify God. David is asking God to fulfill in him what Paul speaks of in II Corinthians 5:16-17:
Therefore, from now on, we regard no one according to the flesh. Even though we have known Christ according to the flesh, yet now we know Him thus no longer. Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.
This renewal of the heart is not simply godly righteousness legally added to a carnal human heart. The new heart is not merely a repair of the old one. David speaks of an entirely new, clean heart and of a mind generated and motivated by God's Holy Spirit. It is a completely new creation of God, paralleling what Adam underwent as God created him in Genesis 1. Was not Adam a new creation at that time?
