Numbers 12:13

And Moses cried unto the Lord,.... With a loud voice, and with great earnestness and importunity, being heartily affected with the miserable condition Miriam was in:

saying, heal her now, O God, I beseech thee; in the original text it is, "O God now, heal her now"; for the same particle is used at the close as at the beginning of the petition; and the repetition of it shows his earnestness and importunity that she might be healed directly, immediately, without any delay; and Moses uses the word "El", which signifies the strong and mighty God, as expressive of his faith in the power of God, that he was able to heal her; and at the same time suggests that none but he could do it; and so Aben Ezra interprets it,

"thou that hast power in thine hand, now heal her;''

this prayer is a proof of his being of a meek, humble, and forgiving spirit.
