hearing & these_‹things› ˱they˲_/were_being/_cut_through ˱in˲_the hearts ˱of˲_them

If your language does not use the passive form in this way, you could state this in active form or in another way that is natural in your language. Alternate translation: [these things cut them to their hearts when they heard them]

Note 2 topic: figures-of-speech / idiom

διεπρίοντο ταῖς καρδίαις αὐτῶν

˱they˲_/were_being/_cut_through ˱in˲_the hearts ˱of˲_them

Here, the expression they were cut to their hearts is an idiom that means the Sanhedrin members became very angry. If your readers would not understand this, you could use an equivalent idiom or use plain language. Alternate translation: [they became furious at Stephen]

Note 3 topic: translate-symaction

ἔβρυχον τοὺς ὀδόντας ἐπ’ αὐτόν

˱they˲_/were/_gnashing their teeth at him

This action expressed their strong anger at Stephen. If there is a gesture with similar meaning in your culture, you could consider using it here in your translation. Alternate translation: [they became so angry at Stephen that they ground their teeth together] or [they moved their teeth back and forth as they looked angrily at Stephen]
