Walk through Amos, verse by verse, with the great Bible Commentaries of Matthew Henry (1662 - 1714) & Adam Clarke (1760 - 1832)
8:12
And they shall wander from sea to sea, and from the north even to the east, they shall run to and fro to seek the word of the LORD, and shall not find it. KJV
{ And they shall be moved (al)together from the sea till to the sea, and from the north till to the east
they shall compass (about), seeking the word of the Lord, and they shall not find.} Wycliffe's Bible
Though they should thus wander from sea to sea, in quest of the word of God, yet shall they not find it. Note, The means of grace are moveable things; and the candlestick, when we think it stands most firmly, may be removed out of its place
