The word of God is quick, and powerful, and sharper than any two-edged sword, piercing even to the dividing (cleaving) asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart
Dividing, cleaving or cloven: Something that is cloven has been cleaved or divided...separated.
In the Old Testament when God was telling his people what they could and could not eat, judging between that which was clean and unclean, he said one of the criteria, in reference to the beast of the field, was that the hoof had to be cloven or divided. This was symbolic of the life they should live and how they WALK with him.
In the temple, in one of the upper rooms, they (the disciples of Jesus) were all with one accord in one place and suddenly the spirit of God moves upon them like a mighty rushing wind and Cloven (Divided) Tongues (Languages) like as of fire (power, boldness, burning on the inside of) appear unto them or is revealed to them and rests upon them (they receive it). They received the Holy Ghost and he filled them and gave them a Heavenly, divided language that is Holy, set apart, powerful that gives them boldness and like fire, burns up chaff and all things that are not of God.
The Holy Spirit gave them a tongue...it’s a tongue of Judgment a tongue that speaks the truth, the word of God, that divides between that which is right and that which is wrong, that which is clean and that which is unclean, that which is good and that which is evil. They spoke it with boldness before the congregations in all the cities and made it known that the same Jesus which they crucified is the Christ and that there is no other salvation anymore but by him. And even at the threat of death spoke they that word with boldness fearing no man but fearing the Father! Not loving this world but loving the father and his kingdom which is to come…AMEN!
