Amos 9:2

Two examples of places, inaccessible to man, in which they are pictured hyperbolically as seeking to escape the Divine hand; Sheol, the deep and cavernous (Isaiah 14:15) abode of the dead, which was located by the Hebrews far down below the earth (Deuteronomy 32:22; Job 26:5; Ezekiel 32:18); and the lofty heights of heaven (Jeremiah 51:53). Comp. the words in which the Psalmist expresses the thought of God's omnipresence, Psalms 139:8; also (with the second clause) Obadiah 1:4.

dig through] The word is used of digging througha wall, Ezekiel 8:8; Ezekiel 12:5; Ezekiel 12:7; Ezekiel 12:12; and the cognate subst. of the act ofrobbers digging intoa house (Exodus 22:2; Jeremiah 2:34); cf. διορύσσειν, Matthew 6:19.
