Isaiah 30:15-17

For thus said the Lord GOD, the Holy One of Israel, “In returning and rest you shall be saved; in quietness and in trust shall be your strength.” But you were unwilling, and you said, “No! We will flee upon horses”; therefore you shall flee away; and, “We will ride upon swift steeds”; therefore your pursuers shall be swift. A thousand shall flee at the threat of one; at the threat of five you shall flee, till you are left like a flagstaff on the top of a mountain, like a signal on a hill.
