Littérature du Second Temple sur Le Deutéronome 27:9

[10] There are indeed some whom it befits to hear but not to speak, those to whom the words apply, “Be silent and hear” (Deut. 27:9). An excellent injunction! For ignorance is exceeding bold and glib of tongue; and the first remedy for it is to hold its peace, the second to give ear to those who advance something worth hearing.

[193] When, however, God  has come to the company  of His friends, He does not begin to say His say before He has addressed each such friend calling him by name, in order that they may prick up their ears, and with stillness and attention so listen to the sacred precepts as to remember them for ever; for it is also said in another place, “Keep silence, and hearken” (Deut. 27:9).

[263] In this way the lips train and exercise us for both purposes, speech and silence, and they teach us to watch for the proper occasion for either. For example: Is something said worth hearing? Oppose it not but pay attention silently according to the command of Moses, “Be still and hear” (Deut. 27:9).
