“For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.” (Hebrews 4:12) “神的道是活泼的，是有功效的，比一切两刃的剑更快，甚至魂与灵，骨节与骨髓，都能刺入剖开，连心中的思念和主意，都能辨明。” （希伯来4：12）
“A double-edged sword”（双刃刀）是一种有潜在危险的武器—它的刃两面都可以切。如果不正确地使用，它对你自己的伤害会和对目标物的伤害一样大。 在使徒保罗所写的《希伯来书》中，他把上帝的话描述为“比一切双刃刀更快，因为“甚至魂与灵，骨节与骨髓，都能刺入剖开，连心中的思念和主意，都能辨明。” 今天，“double-edged sword”（双刃刀/剑）常用于比喻既有好处又有坏处的事物。比如说现代科技，互联网，抗生素等等。
