Acts 10:14

But Peter said, “Certainly not, Lord, for I have never eaten anything defiled and ritually unclean!” ¹ 

Ge 19:18; Ex 10:11; Le 11:1-17; Le 20:25; De 14:1-29; Eze 4:14; Eze 44:31; Mt 16:22; Mt 25:9; Lu 1:60

¹ tn Possibly there is a subtle distinction in meaning between κοινός (koinos) and ἀκάθαρτος (akaqarto") here, but according to L&N 53.39 it is difficult to determine precise differences in meaning based on existing contexts.

sn Peter insisted he would not violate the law by eating anything defiled and ritually unclean. These food laws were one of the practices that distinguished Jews from their Gentile neighbors. The practice made table fellowship with Gentiles awkward. For an example of Jewish attitudes to this, see Dan 1:8-16; 1 Macc 1:41-64; Letter of Aristeas 142; Tacitus, History 5.5.
