The Jerusalem Talmud:
“Forty years before the destruction of the Temple, the western light went out, the crimson thread remained crimson, and the lot for the Lord always came up in the left hand (black). They would close the gates of the Temple by night and get up in the morning and find them wide open” (Jacob Neusner, The Yerushalmi, p.156-157).
The Babylonian Talmud:
“Our rabbis taught: During the last forty years before the destruction of the Temple the lot [‘For the Lord’] did not come up in the right hand (white); nor did the crimson-coloured strap become white; nor did the western most light shine; and the doors of the Hekel [Temple] would open by themselves” (Soncino version, Yoma 39b).
Jesus, Son of God was Crucified in 30AD by most counts, and from that year according to the Jewish record, God no longer took notice of their sacrifices, nor forgave their sins. The Temple was destroyed in AD70, forty years later.
The Lord said to Moses, “How long will these people treat me with contempt? How long will they refuse to believe in me?” I will strike them down” (14:11a, 12a). But Moses interceded for Israel and asked God for forgiveness (14:13-19). God replied, “I have forgiven them, as you asked. Nevertheless, … not one of them will ever see the land I promised on oath to their forefathers” (14:20, 23a). The Lord said to Moses, “[Tell them], ‘In this desert your bodies will fall – every one of you twenty years old or more … who has grumbled against me. Not one of you will enter the land … except Caleb … and Joshua (14:29-30). Your children will be shepherds here for forty years, suffering for your unfaithfulness, until the last of your bodies lies in the desert” (14:33).
Forty years the children of Israel were left with a Temple shell, no forgiveness, nothing to shield them from their murder of the Son of God. Forty years to reconcile with the Son of God. They did not and their Temple was destroyed and they were dispersed. In the place of all mankind – for all mankind was responsible, Jew and Gentile alike – for God had willed that all could become His sons.
