"Belonging to Ya'azanyahu servant of the king"

Possibly the "Jezaniah" from Ma'acah mentioned in...

Jer. 40:8 "So they came to Gedaliah at Mizpah, along with Ishmael the son of Nethaniah, and Johanan and Jonathan the sons of Kareah, and Seraiah the son of Tanhumeth, and the sons of Ephai the Netophathite, and Jezaniah the son of the Maacathite, both they and their men."

2 Kgs 25:23 "When all the captains of the forces, they and their men, heard that the king of Babylon had appointed Gedaliah governor, they came to Gedaliah to Mizpah, namely, Ishmael the son of Nethaniah, and Johanan the son of Kareah, and Seraiah the son of Tanhumeth the Netophathite, and Jaazaniah the son of the Maacathite, they and their men."
