Hey LLOJ, He does mention it just not by that particular name.
1Co 3:10 According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon.
1Co 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ.
1Co 3:12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
1Co 3:13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
1Co 3:14 If any man's work abide which he hath built thereupon, he shall receive a reward.
1Co 3:15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
1Co 3:16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
1Co 3:17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
Now compare that with.
Mat 10:28 "And do not fear those who kill the body, but cannot kill the soul; but rather fear him who is able to destroy both soul and body in Gehenna.
Can you see a bit of a pattern?
But it doesn't say gehenna though.
2Th 1:8 In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:
2Th 1:9 Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;
2Th 1:10 When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day.
2Th 1:11 Wherefore also we pray always for you, that our God would count you worthy of this calling, and fulfil all the good pleasure of his goodness, and the work of faith with power:
2Th 1:12 That the name of our Lord Jesus Christ may be glorified in you, and ye in him, according to the grace of our God and the Lord Jesus Christ.
1Co_6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
2Ti 4:1 I charge thee therefore before God, and the Lord Jesus Christ, who shall judge the quick and the dead at his appearing and his kingdom;
2Ti 4:2 Preach the word; be instant in season, out of season; reprove, rebuke, exhort with
all longsuffering and
doctrine.
2Ti 4:3 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
2Ti 4:4 And they shall turn away their ears from the truth, and shall be turned unto fables.
Rev 20:14 And death and hell were cast into the lake of fire. This is the second death.
Rev 20:15 And whosoever was not found written in the book of life was cast into the lake of fire.
