Ah!
Archimandrite Nikifor’s Biblical Encyclopedia
— an exclamatory interjection expressing joy, sorrow, or sometimes regret or contempt in general (Ezek. 25:3), and almost synonymous with the interjection Oh! found in several places of Holy Scripture, as for instance in Isaiah 1:24 and Э! (“E!”) in Mark 15:29; it is sometimes also used in the sense of an adversative conjunction (Jer. 1:6).
