He made my mouth like a sharpened sword, in the shadow of his hand
he hid me; he made me into a polished arrow and concealed me in his
quiver. He said to me, “You are my servant, Israel, in whom I will
display my splendor.” But I said, “I have labored to no purpose; I
have spent my strength in vain and for nothing. Yet what is due me
is in the Lord’s hand, and my reward is with my God.”
Isaiah 49:2-4
