John Gill Commentary Mark 5:23

"and beseecheth him much, saying, My little daughter is at the point of death: [I pray thee], that thou come and lay thy hands on her, that she may be made whole, and live." — Mark 5:23 (ASV)

And besought him greatly
Used much importunity with him, and was very urgent in his requests:

saying, my little daughter lieth at the point of death ,
or "is in the last extremity"; just breathing out her last; for she was not actually dead when he left her, though she was before he returned, and was at this time, as he might expect, expiring, or really gone; (See Gill on Matthew 9:18).

[I pray thee] come and lay thine hands on her, that she may be
healed, and she shall live ;
expressing faith in the power of Christ to restore his daughter, though in the utmost extremity; yet seemed to think his presence, and the imposition of his hands were necessary to it.
