'Similitude' in the Bible

This similitude spake Jesus to them, and they knew not what the things were that he was speaking to them;

His disciples say to him, 'Lo, now freely thou dost speak, and no similitude speakest thou;

And it is yet more abundantly most evident, if according to the similitude of Melchisedek there doth arise another priest,

with it we do bless the God and Father, and with it we do curse the men made according to the similitude of God;

and happened to them hath that of the true similitude; 'A dog did turn back upon his own vomit,' and, 'A sow having bathed herself -- to rolling in mire.'
