Adam Clarke on Acts 2:26

And my tongue was glad - In the Hebrew it is ויגל כבודי vaiyagel kebodi, "And my glory was glad:" but the evangelist follows the Septuagint, in reading και ηγαλλιασατο ἡ γλωσσα μου, what all the other Greek interpreters in the Hexapla translate δοξα μου, my glory. And what is to be understood by glory here! Why the soul, certainly, and not the tongue; and so some of the best critics interpret the place.
