Exodus 26:4

Exo 26:4 And thou shalt make loops of blue upon the edge of the one curtain from the selvedge in the coupling; and likewise shalt thou make in the uttermost edge of [another] curtain, in the coupling of the second.

Ver. 4. Upon the edge of the one curtain. ] The coupling of these two great curtains together, to make one tabernacle, might signify that the saints both in heaven and earth do make but one Church. Ephesians 1:10 ; Eph 3:15
