It is impossible to say where Tertullian got this reading. Perhaps his LXX. copy might have had (in Ex. xx. 10): Οὐ ποιήσεις ἐν αὐτῇ πᾶν ἔργον σου, instead of συ; every clause ending in σου, which follows in that verse. No critical authority, however, now known warrants such a reading. [It is probably based inferentially on verse 9, “all thy work.”]
