Exodus 22:4 New English Translation

⁴If the stolen item should in fact be found^[a] alive in his possession,^[b] whether it be an ox or a donkey or a sheep, he must pay back double.^[c]

Exodus 22:4 tn The construction uses a Niphal infinitive absolute and a Niphal imperfect: if it should indeed be found. Gesenius says that in such conditional clauses the infinitive absolute has less emphasis, but instead emphasizes the condition on which some consequence depends (see GKC 342-43 §113.o).
Exodus 22:4 tn Heb “in his hand.”
Exodus 22:4 sn He must pay back one for what he took, and then one for the penalty—his loss as he was inflicting a loss on someone else.
