The Hebrew ideal of man was threefold:

“Heart” From Concise Bible Dictionary:

 
The heart is often referred to in scripture as the seat of the affections and of the passions, also of wisdom and understanding—hence we read of “the wise in heart,” also the Lord gave to Solomon “a wise and understanding heart.” It is the center of a man’s being. But before the deluge God’s verdict of man was that every imagination of the thoughts of his heart was only evil continually (Gen. 6:55And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. (Genesis 6:5)). A similar verdict is found in Genesis 8:2121And the Lord smelled a sweet savor; and the Lord said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done. (Genesis 8:21), after Noah came out of the ark. And the Lord said, Out of the heart of man proceed evil thoughts and every form of wickedness (Mark 7:2121For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, (Mark 7:21)). The law required man to love God with all his heart. The reception of the gospel must be in the heart, (Rom. 10:99That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. (Romans 10:9)); and God enables a hearer to receive the good news in “an honest and good heart,” upon which there is fruit (Luke 8:1515But that on the good ground are they, which in an honest and good heart, having heard the word, keep it, and bring forth fruit with patience. (Luke 8:15)). In new creation there is a “pure heart,” the Christian being led by the Holy Spirit (1 Tim. 1:55Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned: (1 Timothy 1:5); 2 Tim. 2:2222Flee also youthful lusts: but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart. (2 Timothy 2:22); 1 Pet. 1:2222Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: (1 Peter 1:22)).

“Soul, Spirit” From Concise Bible Dictionary:

The Hebrew word commonly translated “soul” is nephesh: in many instances this is translated “life” in the AV, as in Jonah 1:1414Wherefore they cried unto the Lord, and said, We beseech thee, O Lord, we beseech thee, let us not perish for this man's life, and lay not upon us innocent blood: for thou, O Lord, hast done as it pleased thee. (Jonah 1:14): “Let us not perish for this man’s life,” or soul. In the New Testament the word ψυχή stands for both “life” and “soul:” “Whosoever will save his ‘life’ shall lose it; and whosoever will lose his ‘life’ for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own ‘soul’? or what shall a man give in exchange for his ‘soul’?” (Matt. 16:25-2625For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. 26For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? (Matthew 16:25‑26)).
The soul, as distinguished from the spirit, is the seat of appetites and desires. The rich man said, “I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, and be merry” (Luke 12:1919And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, and be merry. (Luke 12:19)). That night his “soul” was required of him. The salvation of the soul cannot be distinguished from the salvation of the person.
The SPIRIT is distinctively the higher part of man, it marks the conscious individuality, and distinguishes man thus from the inferior creation. God breathed into man’s nostrils the breath of life, and by this man was set in relation with God, and cannot be really happy separated from Him, either in present existence or eternally. The words are ruach and πνεῦμα, and are the same as constantly used for God’s Spirit, the Holy Spirit, or Holy Ghost, and for the angels as spirits, and for evil spirits.
The word of God is sharp, and able to divide asunder the soul and spirit of a man, though it may not be easy for the human mind to see the division. The apostle prayed for the Thessalonians that spirit (which is probably viewed as the seat of God’s work), as well as soul and body might be sanctified (1 Thess. 5:2323And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. (1 Thessalonians 5:23)). In the Epistle to the Hebrews we read of the “spirits” of just men made perfect: their place is with God through redemption. Here “spirits” apparently signifies the persons apart from their bodies.
The Holy Spirit being given to the Christian, as the spring in him of life in Christ, he is exhorted to pray with the spirit, sing with the spirit, walk in the Spirit, so that in some cases it is difficult to distinguish between the Spirit of God and the Christian’s spirit.
