In his arms.
He blessed God.”
καὶ αὐτὸς ἐδέξατο αὐτὸ εἰς τὰς ἀγκάλας καὶ εὐλόγησεν τὸν Θεὸν
Luke said that Simeon took Jesus into his arms (καὶ αὐτὸς ἐδέξατο αὐτὸ εἰς τὰς ἀγκάλας). He then blessed God (καὶ εὐλόγησεν τὸν Θεὸν). It would seem a little odd for an old man to take a small child under two-months old into his arms without asking the mother if it was okay. However, the blessing of God did not seem out of place here in the Jerusalem Temple.
