The כתב סופר sees these two categories as referring to the two possible times for משיח to come. The hidden one is the fixed date, which is unknown. The revealed one is the date if and when ×‘× ×™ ישר×ל will be חוזר בתשובה, as the פסוק says, “×”×™×•× ×× ×‘×§×•×œ×™ תשמעו.” While the first is independent of our actions, the second is only if we are follow “×ת כל דברי התורה ×”×–×ת”
×ת ×”×—×™×™× ×•×ת הטוב ×ת המות ו×ת הרע
The משך חכמה points out that in פרשת ר××”, it just said ברכה וקללה, but never mentioned .×—×™×™× ×•×ž×•×ª He explains that this is because earlier, the oppurtunity for תשובה had not yet been presented. If a person fails to repent for an עבירה, this worse than the original עבירה (cf שערי תשובה). As such, the עבירה itself is the קללה and the lack of תשובה is the מוות.

The בכורי ×ביב explains the repetition as a reminder that the goal is not merely to enjoy a long life, but a meaningful one.
×•×™×§×¨× ×ž×©×” ליהושע וי×מר ×ליו ×œ×¢×™× ×™ כל ישר×ל חזק ו×מץ
The משך חכמה writes that the words ×œ×¢×™× ×™ כל ישר×ל are connected, via the טעמי המקר×, to חזק ו×מץ. Up until this point, יהושע’s role had been that of משה’s servant, and he was most known for his humility in front of his teacher. As the new ×ž× ×”×™×’, he would need to, publicly, be strong and certain, in order to be able to effectively lead כלל ישר×ל.
