'Custom' in the Bible

They kept also the feast of tabernacles, as it is written, and offered the daily burnt offerings by number, according to the custom, as the duty of every day required;

Be it known now unto the king, that, if this city be builded, and the walls set up again, then will they not pay toll, tribute, and custom, and so thou shalt endamage the revenue of the kings.

There have been mighty kings also over Jerusalem, which have ruled over all countries beyond the river; and toll, tribute, and custom, was paid unto them.

Also we certify you, that touching any of the priests and Levites, singers, porters, Nethinims, or ministers of this house of God, it shall not be lawful to impose toll, tribute, or custom, upon them.
