John Gill Commentary Hebrews 13:19

"And I exhort [you] the more exceedingly to do this, that I may be restored to you the sooner." — Hebrews 13:19 (ASV)

But I beseech you the rather to do this
To pray earnestly; to strive together in their prayers for them, (Romans 15:30–32)

that I may be restored to you the sooner :
Christ's ministers are sometimes hindered from being with their people, through Satan, or his emissaries, creating troubles, or casting them into prison; which might be the apostle's case now; but God can make their way through all; and for this he should be prayed unto.
