It seems you are correct.
Father has indeed gone mad.
Quiet.
Leave those.
But Father,
we may need them for trade. Or for drinking.
We have been commanded to take nothing
save it be our family, provisions, and tents.
Obey your father, Lemuel.
Leave the gold and silver, as the Lord commands.
Tut tut.
We thank Thee for Thy mercy in protecting us
and delivering us from the destruction of Jerusalem.
We pray, Father, that Thou wilt guide us through
this wilderness and that we will have the faith to follow Thee.
