Peter Pett's Commentary on the Bible
Ezekiel 23:5,6
“And she doted on her lovers, on the Assyrians her neighbours, who were clothed with blue, governors and rulers, all of them desirable young men, horsemen riding on horses. And she bestowed her whoredoms on them, the choicest men of Assyria, all of them. And on whoever she doted, she defiled herself with all their idols.”
This is to be seen as very much a potted summary of her history. Assyria were the most prominent of those whom she looked to, and were the ones who in the end brought about her downfall. She saw them, and was dazzled by them, and responded to them, welcoming their gods with open arms, as she had those before Assyria such as Baal Melkart. They were such as would be attractive to any woman, clothed in blue (possibly a sumptuous violet blue), people of authority (the terms are Akkadian loan words meaning district governors and satraps), young and desirable, riding proudly on horseback. And she gave herself to them and doted on their idols.
History tells us how they subjected themselves to Assyria by paying tribute with its accompanying subjection. The Black Obelisk of Shamaneser III depicts Jehu prostrating himself before the king of Assyria and offering tribute (about 840 BC), seeking his assistance against his enemies. Adad Nirari III also speaks of receiving tribute ‘from the territory of Omri', a synonym for Israel. (Omri had been a great Israelite king admired by Assyria). See also 2Ki 15:19-20; 2 Kings 17:3; Hosea 3:1; Hosea 7:11; Hosea 8:9; Hosea 12:1.
So she who should have been gazing at Yahweh and should have been faithful to Him alone, rather turned her gaze on the splendour and power of the world outside and made them the object of her love, as Israel had previously done in Egypt, and that led on to rampant idolatry with all that that involved.
‘Her neighbours.' Some have cavilled at the idea that Assyria could be called Israel's ‘neighbour' (qarob), one who is near. But by the time of Ezekiel the Mesopotamian world and the Egyptian world were the prominent friend/enemy (alternately) of the north and south, and would thus be seen as near in comparison with the further unknown world which was a mystery. They were near enough to be called on for military assistance.
Alternatives suggested have been to relate qarob to a late Hebrew word for ‘war' (qerab), giving the meaning of ‘warrior', a small emendation to the text to make the word mean ‘warriors' based on the Assyrian quradu, or a connection with the qurbutu, an Assyrian officer close to the king and used in intelligence missions and discreet contact.
