This verse sits inside the father's warning about the gang, Proverbs 1:8–19, and opens the gang's quoted pitch (vv. 11–14).
The father performs the gang's own words, and their first word is the hook: "Come with us." The invitation leads with belonging; the blood is item two.
The father's warning about the gang is a drama with a script. It opens with the appeal that will head every lecture, hear your father's instruction, do not forsake your mother's law, and crowns obedience with ornament: garland for the head, chains for the neck (vv. 8–9). Then it stages the danger. Sinners will entice you, and the father does not paraphrase them; he performs their whole pitch (vv. 11–14): the thrill ("let us lie in wait"), the loot ("we shall fill our houses with spoil"), and, most seductive of all, the belonging ("cast in your lot among us, let us all have one purse"). Then he answers it (vv. 15–19): do not walk with them, and here is what they cannot see, the trap they are laying is for themselves. Even a bird avoids a net spread in plain sight (v. 17), but these men are blinder than birds: they ambush their own lives, because greed's way "takes away the life of its owners" (v. 19). The lecture's method is the book's method in miniature: it does not just forbid; it lets the temptation speak at full strength, then teaches the son to see through it to the ending. Note who recruits him: not strangers, peers. The first threat to a young life in this book is not the harlot or the fool but the group that offers brotherhood at the price of blood.
This verse contributes the pitch's opening, and the father's teaching method with it: he quotes the temptation at full strength instead of describing it safely. "Come with us" is the oldest recruitment line on earth, membership offered to a young man who wants nothing more than to belong somewhere. Only after the welcome comes the plan, and the father's quotation keeps its brutality unlaundered: lie in wait, shed blood, ambush the innocent "without cause." Spoken aloud, the pitch indicts itself; that is the point of performing it. The son who has heard the words plainly at home is harder to enchant when they arrive dressed up on the street.
