Numbers 16:38

16:38 As for the censers of these men who sinned at the cost of their lives, they must be made into hammered sheets for covering the altar, because they presented them before the Lord and sanctified them. They will become a sign to the Israelites.”

James 1:22

1:22 But be sure you live out the message and do not merely listen to it and so deceive yourselves.

tn The expression is “in/by/against their life.” That they sinned against their life means that they brought ruin to themselves.

tn The form is the perfect tense with vav (ו) consecutive. But there is no expressed subject for “and they shall make them,” and so it may be treated as a passive (“they shall [must] be made”).
