Swallow deror, from darar, "free, spontaneous motion" (Psalms 84:3). I (See tid=659) 'Agur is probably the "crane", from ga'ar "to chatter", as Latin grus is related to garrio, in Isaiah 38:14, and sus (the Italian zisilla) the "swallow": "like a swallow or a crane." In Proverbs 26:2 the sense is "as the bird ("sparrow") by wandering, as the swallow (deror) by flying, never lights upon us, but flies to the winds, so the curse for which we have given no just cause shall not come" to hurt us; contradicting the common superstition that a curse brings its fulfilment, however undeserved; nay Providence shields His people from Satan's and his agents' malice. Balaam could not curse Israel whom God had blessed (Deuteronomy 23:5), nor Shimei David, nay God requited David good instead (2 Samuel 16:5-12; Psalms 109:28).
