A.T. Robertson Commentary Romans 12:18

"If it be possible, as much as in you lieth, be at peace with all men." — Romans 12:18 (ASV)

As much as in you lieth (το εξ υμων). Accusative of general reference, "so far as what proceeds from you" ("the from you part"). See το κατ' εμε in 1:15. This phrase explains "if it be possible" (ε δυνατον). "All your part is to be peace" (Alford). For "be at peace" (ειρηνευοντες) see 2 Corinthians 13:11.
