Hebrews 13:19

But I beseech you the rather to do this, that I may be restored to you the sooner.

The rather, [ perissoteroos (G4056)] - 'I the more abundantly beseech you.'

To do this - to pray for me.

That I may be restored to you (Philemon 1:22). It is here first he mentions himself so unobtrusively as not to prejudice his Hebrew readers against him, which they would have been had he commenced this, as other letters, with authoritatively announcing his name and apostolic commission.
