John Gill Commentary Joshua 9:12

"This our bread we took hot for our provision out of our houses on the day we came forth to go unto you; but now, behold, it is dry, and is become mouldy:" — Joshua 9:12 (ASV)

This our bread we took hot [for] our provision out of our
houses
These are not the words of the elders to the messengers they sent, continued, but of the ambassadors to the Israelites, pointing to the bread they brought with them, which they pretended was newly baked and took hot out of the oven:

on the day we came forth to go unto you, but now, behold, it is dry ,
and it is mouldy: (See Gill on Joshua 9:5); which they gave as a demonstration and proof that they were come from a far country, as they had asserted.
