1 tn Grk “in which.” The relative pronoun was replaced by the pronoun “it,” and a new sentence was begun in the translation at this point to improve the English style.
2 tn Or “snakes.” Grk “creeping things.” According to L&N 4.51, in most biblical contexts the term (due to the influence of Hebrew classifications such as Gen 1:25-26, 30) included small four-footed animals like rats, mice, frogs, toads, salamanders, and lizards. In this context, however, where “creeping things” are contrasted with “four-footed animals,” the English word “reptiles,” which primarily but not exclusively designates snakes, is probably more appropriate. See also Gen 6:20, as well as the law making such creatures unclean food in Lev 11:2-47.
3 tn Grk “the birds of the sky” or “the birds of the heaven”; the Greek word οὐρανός (ouranos) may be translated either “sky” or “heaven,” depending on the context. The idiomatic expression “birds of the sky” refers to wild birds as opposed to domesticated fowl (cf. BDAG 809 s.v. πετεινόν).
4 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.
