Charles Ellicott Commentary Psalms 64:5

"They encourage themselves in an evil purpose; They commune of laying snares privily; They say, Who will see them?" — Psalms 64:5 (ASV)

They encourage themselves. — Literally, they strengthen for themselves an evil thing (or “word,” margin, Septuagint, and Vulgate), which evidently means that they take their measures carefully and are prepared to carry them out resolutely.

They commune ... — Better, they calculate how they may lay snares privily. The conspirators carefully and in secret go over every detail of their plot.

Who shall see them? — Literally, who shall look to them? This seems at first glance to mean, “who will see the snares?” but this is weak. It may be equivalent to, “who is likely to see us?” the question being put indirectly. But in 1 Samuel 16:7, the expression, “looketh on,” implies “regard for,” which may possibly be the meaning here, “who cares for them?”
