Agreed, although we’re told that Sev is a “militaristic act”:

(KGT 48):  Common militaristic acts also have associated terminology, both verbs (DoHmoH, drive back; Hub, defend; yot, invade; weH, raid [same as yot, really, but with the added connotation of surprise or speed]; HIv, attack, assault; Sev, contain; HeD, retreat, withdraw) and nouns (yot, invasion, raid, incursion; Hub, defense).

For contain (have inside) there is ngaS.  See also Dech surround, qat wrap, encase and wegh confine.

N.B. Do not confuse with the verb {Sev} "contain (an enemy)".

Surely they're related. To merely contain an enemy (as opposed to eliminating them or getting them to surrender) is a temporary solution to a problem, just like a bandage.
