¹ tn The interrogative uses the demonstrative pronoun in its emphatic position: “Why in the world…?” (IBHS 312-13 §17.4.3c).

¹ tn The form is a Piel participle from קָלַל (qalal), meaning in Qal “be light,” in Piel “treat lightly, curse, revile, declare contemptible, treat shamefully.” (See its use in Lev 19:14; Josh 24:9; Judg 9:26-28; 1 Sam 3:13; 17:43; 2 Sam 16:5-13; Prov 30:10-11; Eccl 7:21-22; 10:20.) It is opposite of “honor” (כָּבֵד, kaved; Qal “be heavy”; Piel “honor,” as in 20:12) and of “bless.” This verse then could refer to any act contrary to the commandment to honor the parents. B. Jacob (Exodus, 640) cites parallels in Sumerian where people were severely punished for publicly disowning their parents. “21:15, 17 taken together evoke the picture of parents who, physically and verbally, are forcibly turned out of the house (cf. Prov. 19:26)” (C. Houtman, Exodus, 3:148).
