and I say to you, Make to yourselves friends out of the mammon of unrighteousness, that when ye may fail, they may receive you to the age-during tabernacles.

ἐκλίπῃ eklipē “it may fail”

and I besought for thee, that thy faith may not fail; and thou, when thou didst turn, strengthen thy brethren.'

ἐκλίπῃ eklipē “may fail”

and the sun was darkened, and the vail of the sanctuary was rent in the midst,

and as a mantle Thou shall roll them together, and they shall be changed, and Thou art the same, and Thy years shall not fail.'

ἐκλείψουσιν. ekleipsousin “will never end.”
