"You canker blossom!" 3 Shakespearean Insults
Old English ceace, cece "jaw, jawbone," in late Old English also "the fleshy wall of the mouth." Perhaps from the root of Old English ceowan "chew" (see chew (v.)), or from Proto-Germanic *kaukon (cf. Middle Low German kake "jaw, jawbone," Middle Dutch kake "jaw," Dutch kaak), not found outside West Germanic.
Words for "cheek," "jaw," and "chin" tend to run together in IE languages (e.g. PIE *genw-, source of Greek genus "jaw, cheek," geneion "chin," and English chin); Aristotle considered the chin as the front of the "jaws" and the cheeks as the back of them. The other Old English word for "cheek" was ceafl (see jowl).
A thousand men he [Samson] slow eek with his hond,In reference to the buttocks from c.1600. Sense of "insolence" is from 1840, perhaps from a notion akin to that which led to jaw "insolent speech," mouth off, etc. To turn the other cheek is an allusion to Matt. v:39 and Luke vi:29.

Situated side by side or in close contact: “The commuters were packed in the subway cheek by jowl.”
Smiting on the cheek was accounted a grievous injury and insult (Job 16:10; Lam. 3:30; Micah 5:1). The admonition (Luke 6:29), "Unto him that smiteth thee on the one cheek offer also the other," means simply, "Resist not evil" (Matt. 5:39; 1 Pet. 2:19-23). Ps. 3:7 = that God had deprived his enemies of the power of doing him injury.
