'Certify' in the Bible

See, I will tarry in the plain of the wilderness, until there come word from you to certify me.

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.

These are the ones who 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 were really from Israel):

But I certify you, brethren, that the gospel which was preached of me is not after man.
