Walk through Amos, verse by verse, with the great Bible Commentaries of Matthew Henry (1662 - 1714) & Adam Clarke (1760 - 1832)
9:2
Though they dig into hell, thence shall mine hand take them; though they climb up to heaven, thence will I bring them down: KJV
{If they shall go down till to hell, from thence mine hand shall lead out them; and if they shall ascend
till to heaven, from thence I shall draw them down.} Wycliffe's Bible
Though they dig into hell - Though they should get into the deepest caverns; though they climb up to heaven - get to the most inaccessible heights; I will drag them up from the one, and pull them down from the other.
