Overview
While Scripture does not specifically mention returning knives, biblical principles regarding borrowed property and honest dealings establish that we should return what belongs to another person. The law of restitution and the command to love our neighbor require integrity in all transactions and borrowed items.
Key Scriptures
"The wicked borrows but does not pay back, but the righteous is generous and gives" (Psalm 37:21, ESV).
"Owe no one anything, except to love each other, for the one who loves another has fulfilled the law" (Romans 13:8, ESV).
"If anyone steals an ox or a sheep and slaughters it or sells it, he shall repay five oxen for an ox, and four sheep for a sheep" (Exodus 22:1, ESV).
Application
Promptly return any borrowed knife or tool in good condition, treating others' possessions as you would want yours treated, reflecting Christ's character through trustworthiness and respect for others' property.
