Could the following two lines:

Numbers 10:2 Make thee two trumpets of silver; of a whole piece shalt thou make them: that thou mayest use them for the calling of the assembly, and for the journeying of the camps.

  3 And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation.

taken with:

John 10:7 Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep.

be a picture of:

I Thessalonians 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:

  17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.

and:

I Corinthians 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
