Didache, on Prov 21:6

“He that gathereth treasures by a lying tongue, is vain and foolish, and shall stumble upon the snares of death.”

“Thou shalt not be double-minded nor double-tongued; for to be double-tongued is a snare of death. Thy speech shall not be false, nor empty, but fulfilled by deed. Thou shalt not be covetous, nor rapacious, nor a hypocrite, nor evil disposed, nor haughty. Thou shalt not take evil counsel against thy neighbour. Thou shalt not hate any man; but some thou shalt reprove, and concerning some thou shalt pray, and some thou shalt love more than thy own life.”
