17He that speaketh that, that he knoweth, is a judge of rightfulness or of rightwiseness; but he that lieth, is a guileful witness.
18A man is that promiseth, and he is pricked as with the sword of conscience; but the tongue of wise men is health.
19The lip of truth shall be steadfast without end; but he that is a sudden witness, maketh ready the tongue of leasing.
