Amariah

Amariah ("Name means::YHWH has promised") (ca. 991/0–fl. 898/7–890/89 BC) was the sixteenth high priest of Israel. He served during the last years of the reign of King Jehoshaphat of Judah, including the co-regency of Jehoram, and probably died shortly before the one-year reign of Ahaziah.

Genealogy
He was the grandson of Azariah I and is mentioned in the genealogy of the high priests in the line of Eleazar. The date that Jehoiada died, and his life span of 130 years, are known. Based on that, Amariah was born no later than 3014 AM and died after living about 101 years.

Career
Amariah became high priest shortly after, or perhaps before, the battle in which King Ahab of Israel was killed and Jehoshaphat was barely able to escape unscathed. Jehoshaphat received a reproof from the current prophet, Jehu, and decided to repeat the mission he had mounted in his third regnal year to educate the people on the laws of God. Jehoshaphat confirmed Amariah at that time as high priest and told his people that Amariah was the senior officer in charge of all matters pertaining to God. 

The Kingdom of Judah suffered an invasion by a combined Moabite and Ammonite force, but those forces engaged in fratricide so that Jehoshaphat's forces scarcely had to cast a spear in anger. 

However, Amariah's career was remarkably short, and he died, presumably at the age of 101, after only eight years of service. His son Jehoiada succeeded him.
