Strength from Others
“Those who are a source of strength to others need their own source of strength. The Torah is explicit in telling us how often for Moses that source of strength was God Himself. But even Moses needed a human friend, and it seems, by implication, that this was Miriam. A leader in her own right, she was also one of her brother’s sources of strength. Even the greatest cannot lead alone.”
Miriam, Moses’ Friend (Chukat, Lessons in Leadership, Covenant & Conversation)
