The message that God told prophet Jeremiah was disturbing my mind. He told him about the defeat/destruction of Jerusalem that would stretch for seventy years.” (Source: Kupsabiny Back Translation)

During the first year of his reign, I learned from the Laws that Jerusalem would-remain ruined for a period/[lit. inside] of 70 years, as the LORD said to Prophet Jeremias.” (Source: Hiligaynon Back Translation)
