Midrash sur Isaïe 23:2

"and he heard the Voice": I might think, a low voice; it is, therefore, written "the voice" — the voice explicated elsewhere (Devarim 5:19) "These things the L-rd spoke to all of your congregation … a great voice," and (Shemot 19:16) "and there were thunders (lit., "voices") and lightnings, etc." One verse states "a great voice," and another, (I Kings 19:12) "a voice, silent, thin." How are these two verses to be reconciled? When the Holy One Blessed be He speaks (in His great voice), all are silent, as in (Isaiah 23:2) "Fall silent, you island dwellers. The merchants of Tziddon, the crossings of the sea, would fill you, etc.", and (Vayikra 10:3) "and Aaron was silent." These are the words of R. Yoshiyah. R. Yonathan says: One verse states "a great voice," and another, "a voice, silent, thin." How are these verses to be reconciled? When the Holy One Blessed be He speaks, it is with a great voice; and the angels, in a low voice, as it is written (Isaiah 62:6-7) "… they are never silent. You who 'remind' the L-rd (to rebuild Jerusalem) do not be silent," and (Ibid. 7) "And do not allow Him to be silent until He re-establishes Jerusalem and makes it a glory in the land."
