Hebrews 6:18; Hebrews 12:5; Hebrews 13:22

18 That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:

5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him:

22 And I beseech you, brethren, suffer the word of exhortation: for I have written a letter unto you in few words.
