The original text conveys that the prophet is instructed to act out symbolically what Zedekiah will experience in reality. Gather your belongings, indicating the possessions of someone in transit, in plain view. When they witness your actions, you will leave in the evening as a captive would. It is noted that Zedekiah escaped at night through the breached wall toward the Jordan wilderness, but was captured by the Babylonians, illustrating the destruction of the wall. The phrase "On his shoulders shall he carry" signifies your possessions and all that is typically borne by those fleeing for ease of travel. You will escape in the shadows, unseen by others.
You shall cover your face, either due to the blindness that resulted from his eyes being gouged out by Nebuchadnezzar, or to prevent anyone from recognizing him as king, so that he no longer draws attention from his captors. The statement regarding not seeing the land indicates that he was taken to Babylon bereft of sight and did not behold it. For I have designated you as a sign for the house of Israel; both the words and actions of the prophets serve as symbols and illustrations. In Zechariah, they are referred to as men of signs, foreshadowing what is to come. Similarly, in Hosea, God states, "In the hands of the prophets I shall be likened to them."
Those who interpret Ezekiel as a representation of Christ see the captives as emblematic of the human form, and the breached wall symbolizes the means by which He shattered the gates of hell. Following His resurrection, He was witnessed only by believers and was uplifted as a victor with angelic hosts into heaven. He departs in secrecy, concealing His visage, so that His divine splendor remains unseen by man, and He refrains from observing the earth, ensuring that what is unworthy does not receive the illumination of His gaze. For the eyes of the Lord are upon the righteous, and He withdraws His gaze from the wicked.
These events are narrated to illustrate the truth, so that the hardened hearts of the Israelites may turn to faith through the likeness of humanity. Moreover, He is designated as a sign for the house of Israel, in line with the words, "This man is destined for the fall and the rise of many in Israel, and for a sign to the people of Israel."
