Speak to the Israelites, that they take me a donation from every man as his heart may urge him… The Midrash teaches that after God spoke to Moshe about building the tabernacle-mishkan, Moshe asked “Can Israel really build it?” to which God replied, “Even a single person can build it, as the verse says every man as his heart may urge him every man, each man, can build it.” What does this mean? There is a tradition that Moshe could not work out how to craft the Menorah, in the end he threw a hunk of gold into the fire and it formed itself.  In life we’re only ever asked to do the best we can do, what we can’t do, God finds His own way to complete.
