The words of the wicked are to lie in wait for blood: but the mouth of the upright shall deliver them.
The words of the wicked are to lie in wait for blood - (Proverbs 1:11; Proverbs 1:18.)
But the mouth of the upright shall deliver them - namely, the upright, from the lying in wait of the wicked (Proverbs 11:9). Or, as suits the antithesis, and the expression "the mouth," "the upright," by seasonable counsel of the mouth to those for whom "the wicked" with their "words lie in wait," shall deliver them from the snare. Such counsel the wise Solomon gives, and through heeding it many are delivered (Proverbs 1:10; Proverbs 1:15). So Mercer, Bayne, etc. However, "the mouth of the upright" may be their wise replies to the wicked, who by "words" would ensnare them. Compare Jesus' replies to those who thought to catch Him in His words (Luke 20:1-41; cf. Luke 11:53-54).
