Translation of "law" into Latin

My son, hear the instruction of thy father, and forsake not the law of thy mother.

Audi, fili mi, disciplinam patris tui, et ne dimittas legem matris tuae.

In these same councils they also elect the chief magistrates, who administer law in the cantons and the towns.

Eliguntur in iisdem conciliis et principes, qui jura per pagos vicosque reddunt.

For philosophers have not said anything straight and true that may not be created or confirmed by the people whose cities assign laws.

Nihil enim dicitur a philosophis, quod quidem recte honesteque dicatur, quod non ab iis partum confirmatumque sit, a quibus civitatibus iura discripta sunt.
