The KJV has the curious rendering of : Be of good courage, and let us play the men... (2 Samuel 10:12) Coverdale : Take a good corage vnto the, and let us be strong... Geneva : Be strong & let us be valiant ... Young's Literal : be strong and strengthen thyself... Darby : Be strong, and let us shew ourselves valiant ... NASBU : Be strong, and let us show ourselves courageous... NET Bible : Be strong. Let's fight bravely ... HCSB : Be strong! We must prove ourselves strong ... NLTse : Be courageous! Let us fight bravely ... TNIV : Be strong, and let us fight bravely ... Methinks the KJV was too idiomatic here. It didn't need to be so dynamic.
