CAIN, who was he?

CAIN was the first one born on earth to the original human pair, Adam and Eve. The name Cain is derived from the root word 'qa-nah' that means 'to acquire.' Through him, every soul was placed in bondage, and God's plan to protect and liberate his people was always there from the beginning of human time.
CAIN became a cultivator of the ground, that was understood as a kind of craft work over the ground. ABEL (a breath; vapor), the younger brother of CAIN, as a man he became a herder of sheep.
At the expiration of some time, both of them brought offerings to be presented to God, feeling the need to gain God's favor.
CAIN's offering of some fruits of the ground, however, was not looked upon with any favor by God. It was not made from a sincere heart. It points out that his choices of fruit were not of the best ones. He did not care about that offering making it looks that it was not important to him.
ABEL's offering is specified to have been of the firstlings of his flock, even their fatty pieces, showing his affection to God from a very sincere heart.
CAIN's offering lacked the motivation of Faith that made ABEL's offering acceptable. God who reads the heart of man knew about the wrong attitude of Cain, but he needed to be tested by God and his rejection of the offering resulted in Cain's wrong disposition being made clearly manifest. The personification of sin was taking place in Cain's flesh and he began now to conceive hate, strife, jealousy, fits of anger, etc. God did not abandon him, instead, he began to show him that exaltation could be his by simply turning to doing good, but he chose to ignore God's counsel to master over the sinful desires that lurked at the door craving to dominate him. This is the symbolism of Israel when they rebelled against God and chose the path of sin.
CAIN attacked ABEL, killing him and thereby becoming the first human murderer. As such he could be said to have voluntarily originated with the wicked one who is the father of man-slayers as well as of  the lie.
CAIN's callous response to God's inquiry as to ABEL's whereabouts was further evidence of his attitude; certainly it was not an expression of repentance or remorse but a lying retort: I do not know. Am I my brother's guardian?"
God's sentencing of CAIN to banishment from the ground and the curse already upon the earth increased in the flesh of Cain. As a result, the earth would not respond to Cain's cultivation effort.
CAIN expressed regret over the severity of his punishment and anxiety to the possibility of ABEL's murder being avenged upon him, but still no sincere repentance.
God set up a sign for CAIN to prevent his being killed. It consisted of God's solemn decree itself, known and observed by others.
CAIN went into banishment in the LAND of FUGITIVENESS to the EAST OF EDEN, taking with him his wife. Following the birth of his son Enoch, CAIN engaged in building a city, naming it for his son.
CAIN's descendants are listed in part and include men who distinguished themselves in nomadic stock raising, the playing of musical instruments, the forging of metal tools, also practicing polygamy and violence.
