Then they (l) cried with a loud voice in the Jews' speech unto the people of Jerusalem that [were] on the wall, to affright them, and to trouble them; that they might take the city.
(l) Their words are written, (Kg2 18:19).
And they spake against the God of Jerusalem, as against the gods of the people of the earth, [which were] the (m) work of the hands of man.
(m) Which were invented, made and authorized by man.
