From Middle English sheth, shethe (“holder for a sword, knife, etc., scabbard, sheath”)[and other forms], from Old English sċēaþ (“sheath”),^[1] from Proto-West Germanic *skaiþiju, from Proto-Germanic *skaiþiz (“sheath; covering”), from Proto-Indo-European *skey- (“to dissect, split”) (possibly from the notion of a split stick with a sword inserted).

The English word is cognate with Danish skede, Dutch schede, Icelandic skeið, German Scheide, Low German scheed, Norwegian skjede.
