'Certify' in the Bible

These are the ones that came up from Tel Melah, Tel Harsha, Kerub, Addon, and Immer (although they were unable to certify their family connection or their ancestry, as to whether they really were from Israel):

We certify the king that, if this city be builded again, and the walls thereof set up, by this means thou shalt have no portion on this side the river.

We asked their names also, to certify thee, that we might write the names of the men that were the chief of 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.
