וַיָּ֣חֶל ע֔וֹד שִׁבְעַ֥ת יָמִ֖ים אֲחֵרִ֑ים וַיֹּ֛סֶף שַׁלַּ֥ח אֶת־הַיּוֹנָ֖ה מִן־הַתֵּבָֽה׃
Aspettò ancora altri sette giorni, indi tornò a mandar la colomba fuori dell’arca.
Rashi on Genesis
ויחל AND HE STAYED — The word means waiting, as (Job 29:21) “Unto me they gave ear and waited (ויחלו)”, and it occurs frequently in the Scriptures.
Radak on Genesis
ויחל, the root of this word is חול, it is used in the transitive mode, הפעיל, similar to Judges 3,25 ויחולו עד בוש, “they waited a long time.”
