Nineteen are the years in a "machzor katan" - the cycle of regular and leap years in the Jewish calendar.
Nineteen days is the longest possible tzara'at-quarantine. (Nega'im 3:8)
Nineteen are the books of Tanach that the Christians agree count as a single book each.
(Of the 24 books of the Tanach, Christians split each of Samuel, Kings, Chronicles, Ezra/Nechemiah, and Trei Asar into two or more books. That leaves nineteen. 5 of the Chumash + 5 Megilos + Yehoshua Shoftim Yishaya Yirmiya Yechzkel + Tehilim Mishlei Iyov + Daniel = 19. )
19 were the years that Am Israel dwelled in Kadesh, and nineteen years they were wandering about aimlessly (see Rashi in Devarim 1:46)
19 is the day of Kislev when R' Shneur Zalman of Liadi was released from prison.
