"Speak up for those who cannot speak for themselves, for the rights of all who are destitute. Speak up and judge fairly, defend the rights of the poor and needy" (Prov. 31:8-9.)
We are called to speak up for others when we see them in a position of need, in a situation where speaking up for themselves is difficult, insufficient or impossible.
And we find ourselves, at times, needing help like Moses who needed his brother, Aaron, both to help him speak and to hold up his weary arms.
Whether we are the source of help or the receiver, we need one another.
