For the temple "David prepared iron in abundance for the nails for the doors of the gates, and for the joinings." 1 Chronicles 22:3; but apparently gold nails were used for some parts of the interior. 2 Chronicles 3:9 . The tent pegs were also called nails, though made most probably of hard wood, and perhaps pointed with iron. It was with a tent peg that Jael killed Sisera. Judges 4:21,22 . In houses in the East many articles are hung upon nails for safety, hence 'a nail in a sure place,' denotes security and is figurative of the safety of anything that depends upon God. Isaiah 22:23,25; cf. Ecclesiastes 12:11; Zechariah 10:4 .
Nails pierced the hands and feet of the Saviour when they crucified Him, the marks of which He showed to the disciples after His resurrection, John 20:20,25; and which marks He still retains. Zechariah 13:6 .
