Reading edition
64 That if has no connection with give, is manifest from the cognate forms; Goth. jabai, Frisic jef, Ang. Sax. gif, Old Ger. ibu, Lettish ja, all meaning primarily “in which or in that case, or supposition.” “Jabai—from which the other Germanic forms are descended—appears to have originally been a dative or instrumental case of ja, analogous to tubya = Latin tibi: compare ibi, ubi, Gr. βίῃφι, Slavonic tebje = tibi.”—Garnett.—F.
