The inheritance of Simeon came out of the share of Judah, because Judah's portion turned out to be more than they needed. That's how the people of Simeon came to get their lot from within Judah's portion.
wow what an amazing concept, God! we get to be generous because you overflow us with more than what we need so we can give not just something trivial but something as significant as an entire clan's inheritance! thank you lord that we can believe you for more than what we need, for more than our own concerns, more than what we believe for ourselves and our family and all our concerns to look to others and start believing you for them and everyone connected to them. thank you lord that we can look to what we have from you, what we have now in our hands, we don't have to wait for something grand and spectacular to come (although we are not holding you back from sending so) for us to look outwards and bless people around us. all from you, by you, for you.
