In FMSD ܕܒܝܪ is distinguished from ܧܘܠܝܛܝܐ at 12:b:11. The latter seems to refer to the rules and regulations for monastic life, the former to the way they are carried out.
The passage from Targum Chronicles is strange in that the parallel passage in 1Kgs. uses the normal word פתגם to render Biblical Hebrew דבר. So we have here taken it to refer to conduct instead of speech.
