'Acute' in the Bible

And the queen of Sheba hath heard of the fame of Solomon, and cometh in to try Solomon with acute sayings, to Jerusalem, with a very great company, and camels bearing spices and gold in abundance, and precious stone; and she cometh in unto Solomon, and speaketh with him all that hath been with her heart,

For understanding a proverb and its sweetness, Words of the wise and their acute sayings.

Do not these -- all of them -- against him a simile taken up, And a moral of acute sayings for him, And say, Woe to him who is multiplying what is not his? Till when also is he multiplying to himself heavy pledges?
