History reveals that the decree to restore and to rebuild Jerusalem occurred in 457 B.C., and thus this date is the starting point for both the 70 weeks (or 490 prophetic days or literal years) as well as the 2300 day/year prophecy.
Historia inafunua kuwa amri ya kuutengeneza na kuujenga upya Yerualemu ilitokea mwaka 457 KK, na hivyo tarehe hii ndiyo mwanzo kwa vyote viwili--majuma 70 (au siku za unabii 490 au miaka halisi) na hali kadhalika unabii wa siku/miaka 2300.
