Numbers 10:7

When the congregation is to be gathered together— Lowman observes, that as there were no legislative powers intrusted any where in this constitution, the national revenue settled, and no soldiery in pay, all holding their estates by military service; there was no reason for new taxes: so that the Hebrew congregation, or parliament, could have no business either to make new laws, or to raise money. The things, therefore, in which the consent and authority of the people were requisite, and for which the congregation was to be convened, were war and peace with neighbouring nations; differences between tribes; and receiving and establishing principal officers and magistrates.
