Judges 18:9
And they said, Arise, that we may go up against them: for we have seen the land, and, behold, it is very good: and are ye still? be not slothful to go, and to enter to possess the land. And they said, Arise, that we may go up against them: for we have seen the land, and, behold, it is very good: and are ye still? be not slothful to go, and to enter to possess the land.
The chapters Judges 17-21 record events from the early part of the judges period rather than the end, coming after the main story of the book ends with chapter 16. The verse belongs to one of the book's two concluding episodes, the account of the Danites' move to establish a sanctuary at Dan. In the verse the Danite scouts report that the land at Laish is very good and prosperous and ready to be possessed, and urge their people to act promptly and without delay to go and possess it. Acting on that encouragement, the Danites traveled north with six hundred armed warriors, seized the town and territory they had selected for a home, and renamed it Dan.
There they established idolatrous worship that continued until the ten tribes went into captivity, and that prior worship made it easier for Jeroboam later to set up a golden calf at Dan. The verse stands in a pitiful and sad record of backsliding, grave moral disorder, transgression, and constant lapsing into idolatry from the time when people did what seemed right to themselves, bringing disgrace and punishment that no one suffers with impunity. That condition is shown in putting conventional hospitality above female virtue and loyalty to a tribe above rendering justice, a condition still seen today that never gives excuse for sin. The account connected with the verse is associated with Dan's first apostasy, which is suggested as a reason the tribe was omitted from the 144,000 in the sealing work.
