Pensamento Judaico sobre Isaías 43:22

The Midrash Tanchuma on Parshat Vayechi states that Jacob was prevented from disclosing part of the future to his sons, because when he called them in he failed to call on G-d’s Presence at the same time. A trusted servant who had the complete run of the king's household once determined to give his sons the status of free men and to tell them where the documents confirming this status could be obtained. The king, divining the servant's intention, positioned himself above the servant. Thereupon, the servant, fearful of being caught in an act of disloyalty, began to exhort his sons to promise continued loyal service to the king. Similarly, Jacob called in his sons to tell them about the time their exile would come to an end. Immediately, G-d appeared, wanting to know, "Why have you invited them without inviting Me?" This is the meaning of Isaiah 43,22, "And Me you have not called, Jacob!" As soon as Jacob realized this, he began to tell his sons that they should declare that they would serve the Lord just as their fathers had done, i.e. "the Lord before whom my fathers have walked" (48,15). The sons responded saying, "We know what is in your heart. As you are true to only one Master, so we too will serve only one Master" (shema yisrael). When Jacob heard this, he responded by saying, "Blessed be the name of His glorious Majesty, forever."
