Who does not walk in the counsel of the wicked…
The Hebrew word for walk also means to come and go, depart, proceed, to move and go away. It can also be translated as your manner or way of life (i.e.—your walk).
Wicked also means ungodly and criminal, and specifically are those hostile to God.
If you want to be blessed, do not walk in the advice of those who are hostile to God; do not make it a part of your life. Another way to put it, while you are coming and going, do not accompany the wicked.
… or stand in the way of sinners. (Psalm 1:1c)
The Hebrew word for stand means as to remain, endure; to take one’s stand, to persist, and become a servant of such.
Here you’re no longer walking, but are taking a stand, not against sinners, but with sinners. You could also say that you have become a slave to sin.
Jesus replied, “I tell you the truth, everyone who sins is a slave to sin. (John 8:34)
…or sit in the seat of mockers. (Psalm 1:1d)
The Hebrew word for sit also means dwell, remain, and abide. It also has a meaning as to be set (in one’s ways).
Seat has similar meanings to sit: dwell, dwelling, assembly. Mockers means scorner, scoffer, and interpreter, one who should translate but instead of bringing understanding, makes it a mockery.
Finally our dwelling place is no longer with the godly, but the ungodly. With whom do you live?
Better is one day in your courts than a thousand elsewhere; I would rather be a doorkeeper in the house of my God than dwell in the tents of the wicked. (Psalm 84:10)
Note the downward spiral, the devolution as it were in our actions: from walking to standing to sitting with the ungodly.
Even though this part of the verse has dealt with that which we are NOT to do, the following verse shows us what we are to do: “But his delight is in the law of the Lord,
And in His law he meditates day and night.” May God give you the wisdom to know the difference between what to do, and what not to do.
