EZEKIEL 3:15
 

[NKJV] — Then I came to the captives at Tel Abib, who dwelt by the River Chebar; and I sat where they sat, and remained there astonished among them seven days.

Why do I find men sitting idle outside by the streets in the morning, doing nothing but either discussing politics, gossipping about someone or group, watching and marking those passing by who are going to work or business, and when I pass by them without talking to them nor greeting them, it will seem as if I am being disrespectful and malicious? Must elderly people be sitting by the gates and streets doing nothing meaningful to add value, but expecting anyone who passby to greet them or gift them?
 

Going by this Bible verse alone, I say those Captives in Babylon were neither ladened under forced labor nor tasked unlike those in the bondage of Egypt before Moses came to them.  They just sat idling by the river Chebar, doing nothing but gossip and remembering Zion: and the only thing their taskmasters required of them to do for them, they still would not do it because they were showing religious supremacy or holier than you attitude towards those who carried them to captivity.
 

You were carried captives into their land, but there they did not abuse, did not use you to build their cities, neither did they exploit you as the Egyptians did to some of your ancestors; rather the Babylonians recruited some of your talented men and promoted them in government power, brought some of your royal sons into university of the king, allowed you to carry your musical instruments and to sit by the River as long as you wanted during the captivity or exile, without forcing you to do works, to dig mines, to build cities, but the only thing they pleaded from you was to sing just one of the songs of Zion for them. But as soon as they asked you for song you rebelliously hanged your musical instruments, and  you even despised them, saying, "How can we sing the Lord's song in a strange land?" If the land is a strange land does that mean the Land is not the Lord's Land? Is the earth not the Lord's and the fullness therefore? What is wrong with singing the Lord's song in the Lord's land that is strange to you?
 

[Psalms 137:1-4] — "By the rivers of Babylon, there we sat down, yes, we wept, when we remembered Zion. We hanged our harps on the willows in the middle thereof; because there they that carried us away captive required of us a song; and they that wasted us required of us mirth, saying, Sing us one of the songs of Zion. How shall we sing the LORD's song in a strange land?"
 

The Lord of the songs Himself had described you as "Rebellious People" and He sent Ezekiel to you, not to require a song from you that sat by the River of Babylon called Chebar in Tel-Abib, but to show you "Thus says the Lord." For "Thus says the Lord" is far greater and more important than "All the Songs of Zion."

But in the Bible verse above, though Ezekiel was borne of the Spirit to a Tel-Abib to the Captives by the river, Ezekiel only sat with them seven days among them by that river being astonished and without uttering any word of thus says the Lord to them, as the three friends of Job sat seven astonished at him:
 

[Job 2:12‭-‬13 BSB] — When they lifted up their eyes from afar, they could barely recognize Job. They began to weep aloud, and each man tore his robe and threw dust in the air over his head. Then they sat on the ground with him for seven days and seven nights, but no one spoke a word to him because they saw how intense his suffering was.
 

Ezekiel was showing astonishment by sitting in silence among them for seven days, whereas God sent him to show "Thus says the Lord" not show "Shocking Astonishment" to the captives. For this reason, God may begin to warn Ezekiel that he was supposed to be the watchman among them, and his responsibility is to hear the Warning of God and prophesy, preach or warn those people, and not sitting in astonishment among them seven days without speaking the Word or delivering the message to them.
