and if so taken here, as Arama interprets it, it will make the sense agree with Ps 140:3; and may be read in connection with the following clause, thus: "let the poison of those that compass me about, [even] the mischief of their lips, cover them" ; or the labour of them : let the lies and calumnies they have so industriously spread, and took so much pains to propagate to the hurt of others, like deadly poison, cover them with shame and confusion; and the mischief they have boasted of, and gave out that they would do, let it come upon them on all sides, and utterly ruin and destroy them.
