Yehezkiel 4:13

4:13 And the Lord said, “This is how the people of Israel will eat their unclean food among the nations ¹  where I will banish them.”

Daniel 1:8

1:8 But Daniel made up his mind ²  that he would not defile ³  himself with the royal delicacies or the royal wine. ⁴  He therefore asked the overseer of the court officials for permission not to defile himself.

Kisah Para Rasul 10:14

10:14 But Peter said, “Certainly not, Lord, for I have never eaten anything defiled and ritually unclean!” ⁵ 

[4:13]  ¹ sn Unclean food among the nations. Lands outside of Israel were considered unclean (Josh 22:19; Amos 7:17).

[1:8]  ² tn Heb “placed on his heart.”

[1:8]  ³ tn Or “would not make himself ceremonially unclean”; TEV “become ritually unclean.”

[1:8]  sn Various reasons have been suggested as to why such food would defile Daniel. Perhaps it had to do with violations of Mosaic law with regard to unclean foods, or perhaps it had to do with such food having been offered to idols. Daniel’s practice in this regard is strikingly different from that of Esther, who was able successfully to conceal her Jewish identity.

[1:8]  ⁴ tn Heb “with the delicacies of the king and with the wine of his drinking.”

[10:14]  ⁵ 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.

[10:14]  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.
