I. ‎זִיז‎ noun masculine^{Ps 80:14*} collective moving things (i.e. beasts) (etymology & exact meaning still rather dubious, compare Che^{OP 472} and on Ps 50:11 Thes and others √ ‎זוז‎; De Ps 50:11 compare Assyrian zizânu, collective reptiles, Dl^{S. 74 f.} from a ‎זִאזֵא‎ compare move to and fro, agitate (compare ‎זוע‎); others compare Assyrian zâzu, abundance see II. ‎זוז‎, so even Di Isa 66:11 this hardly suits Ps 80:14* ᵑ7 ‎זִיזָא‎ worm); **on Assyrian zîzê, teats, see RFHarper^{AJSL xiv (1897-1898), 174}. — only construct ‎זִיז שָׂדַי‎ Ps 50:11 the moving things of the field, as all known to ‎׳‎‎י‎ (|| ‎עוֺף הָרִים‎; also in vPs 50:10 ‎חַיְתוֺיָֿ֑עַר‎, etc.); figurative of enemies of Israel Ps 80:14* (|| ‎חֲזִיר מִיָּ֑עַר‎).

Chald.} who proposes, plausibly, ‎מִבִּיזִ‎, compare Aramaic PS⁵⁰², ‎ביזא‎; Arabic pap).
