Quoting Commentary for II Kings 20:17

And the children of Babylon came to her for a bed of love They made a covenant together, and I say that this is said concerning Hezekiah, who rejoiced about the emissaries of Merodach-baladan (Isa. 39, II Kings 20), and he fed them at his table and showed them his entire treasure house. This resembles the prophet’s statement (verse 14), “men engraved on the wall,” because they came from a distant land, and the Chaldeans were not frequent visitors to them, as it is said (Isa. 39:3): “They have come to me from a distant country,” and from seeing their faces once, they became endeared to him. And the Holy One, blessed be He, became wroth with him because of this matter, as it is written (Isa. 36:6, II Kings 20:17): “Behold a time will come when everything in your palace...will be carried off, etc.,” and in (II) Chronicles (32:25): “But Hezekiah did not pay back according to the benefit they had done for him, but his heart became haughty; therefore, wrath came upon him and upon Judah, etc.”
