Proverbs 29:5

5 A man who flattereth his neighbour Spreadeth a net for his steps. Fleischer, as Bertheau: vir qui alterum blanditiis circumvenit; but in the על there does not lie in itself a hostile tendency, an intention to do injury; it interchanges with אל, Psa 36:3, and what is expressed in line second happens also, without any intention on the part of the flatterer: the web of the flatterer before the eyes of a neighbour becomes, if he is caught thereby, a net for him in which he is entangled to his own destruction (Hitzig). החליק signifies also, without any external object, Pro 28:23; Pro 2:16, as internally transitive: to utter that which is smooth, i.e., flattering. פּעמיו is, as Psa 57:7 = רגליו, for which it is the usual Phoenician word.

Those may be said to flatter their neighbours who commend and applaud that good in them (the good they do or the good they have) which really either is not or is not such as they represent it, and who profess that esteem and that affection for them which really they have not; these spread a net for their feet. 1. For their neighbours' feet, whom they flatter. They have an ill design in it; they would not praise them as they do but that they hope to make an advantage of them; and it is therefore wisdom to suspect those who flatter us, that they are secretly laying a snare for us, and to stand on our guard accordingly. Or it has an ill effect on those who are flattered; it puffs them up with pride, and makes them conceited and confident of themselves, and so proves a net that entangles them in sin. 2. For their own feet; so some understand it. He that flatters others, in expectation that they will return his compliments and flatter him, does but make himself ridiculous and odious even to those he flatters.

29:5 Flattery is usually a trap to taking advantage of someone (7:21-22; 26:23).
