But what was the message sent by his sisters? “Lord, behold, he whom You love is ill.”
They did not say, “Come,” for the intimation was all that was needed for One who loved.
They did not venture to say, “Come and heal him,” nor did they venture to say, “Command there, and it shall be done here” …
These women said nothing like this, but only, “Lord, behold, he whom You love is ill” —
as if to say: It is enough that You know. For You are not one that loves and then abandons.

St. Augustine, On the Gospel of John
