³ sn Sarah’s words play on the name “Isaac” in a final triumphant manner. God prepared “laughter” (צְחֹק, ts^ekhoq) for her, and everyone who hears about this “will laugh” (יִצְחַק, yitskhaq) with her. The laughter now signals great joy and fulfillment, not unbelief (cf. Gen 18:12-15).

² sn The subject of this proverb is not simply a deceiver, but one who does so out of jest, or at least who claims he was joking afterward. (The LXX adds that he says this “whenever he is discovered.”) The participle מְשַׂחֵק (m^esakheq) has the idea of “laughing, mocking”; in this context it might convey the idea of “kidding” or “joking.” The point is that such practical joking is immature and often dangerous. To the foolish deceiver it might all seem like fun, like sport, but it can destroy people. One cannot trifle with dangerous weapons, or put them in irresponsible hands; likewise one cannot trifle with human relationships. W. G. Plaut notes, “The only worthwhile humor is that which laughs with, not at others” (Proverbs, 270).

⁴ sn The Hebrew word מְצַחֵק (m^etsakheq), from the root צָחַק (tsakhaq, “laugh”), forms a sound play with the name “Isaac” right before it. Here it depicts an action, probably caressing or fondling, that indicated immediately that Rebekah was Isaac’s wife, not his sister. Isaac’s deception made a mockery of God’s covenantal promise. Ignoring God’s promise to protect and bless him, Isaac lied to protect himself and acted in bad faith to the men of Gerar.

² tn The Piel participle used here is from the same root as the name “Isaac.” In the Piel stem the verb means “to jest; to make sport of; to play with,” not simply “to laugh,” which is the meaning of the verb in the Qal stem. What exactly Ishmael was doing is not clear. Interpreters have generally concluded that the boy was either (1) mocking Isaac (cf. NASB, NIV, NLT) or (2) merely playing with Isaac as if on equal footing (cf. NAB, NRSV). In either case Sarah saw it as a threat. The same participial form was used in Gen 19:14 to describe how some in Lot’s family viewed his attempt to warn them of impending doom. It also appears later in Gen 39:14, 17, where Potiphar accuses Joseph of mocking them.
