Haven’t I ordered you, ‘Be strong, be bold’? So don’t be afraid or downhearted, because The LORD your G-d is with you wherever you go.”
But while he was thinking about this, an angel of The LORD appeared to him in a dream and said, “Yosef, son of David, do not be afraid to take Miryam home with you as your wife; for what has been conceived in her is from the Ruach HaKodesh.
There is a theme of courage in the verses I picked. Joshua is on a mission from G-d. He has seen the defeat of Egypt, the miraculous sojourn through the Wilderness and now he is on the frontier about to head into captive territory that he has been tasked to free. Along the way he has to lead a people who are the children of slaves into becoming a nation of priests so that they can fulfill a holy destiny of connecting the whole world to the one true G‐d.
Joseph is a good man. He is looking forward to entering into a marriage with a girl even as his people live under the occupation of a pagan Empire. When he learned of Miriam’s apparent infidelity, he wanted to deal with it in the best way he knew: by quietly divorcing her. He contemplated this but before he could act, G-d intervened. Joseph was given a noble task: to take on a woman and son who would always carry with them a stigma. He was given a mission like Joshua to lead and shepherd a family through parts unknown.
Joshua and Joseph were commanded to have courage and not be afraid. Fear is a corrosive element and it has to be put in check if we are to live the lives G-d jas planned for us.
