2 Kings 18:18

And when they had called to the king, there came out to them Eliakim the son of Hilkiah, which was over the household, and Shebna the scribe, and Joah the son of Asaph the recorder.

When they had called to the king - Hezekiah did not make a personal appearance, but commissioned his three principal ministers to meet the Assyrian deputies at a conference outside the city walls.

Eliakim - lately promoted to be master of the royal household, prefect or chamberlain of the palace (Isaiah 22:20).

Shebna - removed for his pride, presumption, and unconstitutional politics-for a contrast is evidently implied between him and his predecessor, who is called "a servant of Yahweh" (Isaiah 22:15) - through the influence of Isaiah, from that office, though still х hacopeer (H5608)] the private royal secretary.

Joah ... the recorder, х hamazkiyr (H2142)] - i:e., the keeper of the chronicles-an important office in Eastern countries.
