Titus 2:1
But speak thou the things which become sound doctrine:
1 Timothy 1:10
For lewd persons, for them that defile themselves with mankind, for men-stealers, for liars, for perjured persons, and if there is any other thing that is contrary to sound doctrine,
Titus 1:9
Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers.
1 Timothy 6:3
If any man teacheth otherwise, and consenteth not to wholesome words, even the words of our Lord Jesus Christ, and the doctrine which is according to godliness,
2 Timothy 1:13
Hold fast the form of sound words, which thou hast heard from me, in faith and love which is in Christ Jesus.
Titus 2:11-14
For the grace of God that bringeth salvation hath appeared to all men,
Titus 3:8
This is a faithful saying, and these things I will that thou affirm constantly, that they who have believed in God may be careful to maintain good works. These things are good and profitable to men.
