2SA 4:4

4 And a son feeble in his feet was to Jonathan, the son of Saul; and he was five years eld [[or old]], when the messenger came from Saul and Jonathan, from Jezreel, telling that they were dead. Therefore his nurse took him, and fled; and when she hasted to flee, she felled down, and the child was made lame; and the name of the child was Mephibosheth.
