Hebrews 13:19

the rather--Greek, "I the more abundantly beseech you." to do this--to pray for me. that I may be restored to you-- (Plm 1:22). It is here first in the letter he mentions himself, in a way so unobtrusive, as not to prejudice his Hebrew readers against him, which would have been the result had he commenced this as his other Epistles, with authoritatively announcing his name and apostolic commission.

The apostle, having treated largely of Christ, and faith, and free grace, and gospel privileges, and warned the Hebrews against apostasy, now, in the close of all, recommends several excellent duties to them, as the proper fruits of faith (v. 1-17); he then bespeaks their prayers for him, and offers up his prayers to God for them, gives them some hope of seeing himself and Timothy, and ends with the general salutation and benediction (Heb 13:18 to the end).
