'Know' in the Bible

that search may be made in the book of the records of thy fathers: so shalt thou find in the book of the records, and know that this city is a rebellious city, and hurtful unto kings and provinces, and that they have moved sedition within the same of old time; for which cause was this city laid waste.

And thou, Ezra, after the wisdom of thy God that is in thy hand, appoint magistrates and judges, who may judge all the people that are beyond the River, all such as know the laws of thy God; and teach ye him that knoweth them not.
