In this week's Torah portion, Va'era, God hears the cries of the Israelites and promises to free us from bondage. But when Moshe comes to the children of Israel to tell them that, Torah says:

וְלֹ֤א שָֽׁמְעוּ֙ אֶל־מֹשֶׁ֔ה מִקֹּ֣צֶר ר֔וּחַ וּמֵעֲבֹדָ֖ה קָשָֽׁה׃

They did not hear Moshe, because of kotzer ruach and hard servitude.

Rashi explains the phrase kotzer ruach by saying, "If one is in anguish his breath comes in short gasps and he cannot draw long breaths." For the Sforno, kotzer ruach means "it did not appear believable to their present state of mind, so that their heart could not assimilate such a promise."
