ציטירנדיקער פּירוש אויף יחזקאל 21:27

set your face southward – Setting one’s face indicates that the prophet is preparing himself towards whichever side he will prophecy. This verse is referring to the prophecy which he spoke concerning the siege of Jerusalem from verse thirteen and on. There he described how Nevuchadnezzar used divinations to determine if he should go left toward Rabbat Bnei Amon or right toward Jerusalem. The lot fell on the southern path, meaning that he should go to the right, as it says “At his right was the divination to Jerusalem…” (Ezekiel 21:27):

וקסמים בידו, they brought along charms of their own to forestall Bileam saying that he did not have any of these charms handy. We read in Ezekiel 21, 27-28: “in his right hand the קסם, sorcery, indicated Jerusalem, to appoint commanders to urge on to murder. But it was for them as a vain divination, קסם שוא, etc.”
