"The man and the woman are slow."
Translation:הגבר והאישה איטיים.
I think איש means a male person (it can refer to a husband), גבר means a man (it can refer to a soldier, cf. adj גבור, "strong," and biblical גבור חיל), while אדם means human being and can refer to either male or female in some contexts (Gen 1:27) and so is equivalent to ancient Greek ἄνθρωπος. איש is equivalent to ancient Greek ἀνήρ, a male person. There are important exceptions to these equivalencies, but those are general designations to start with.
