'Deficiency' in the Bible

Do not refuse one another, unless perhaps it is just for a time and by mutual consent, so that you may devote yourselves to prayer and may then associate again; lest the Adversary begin to tempt you because of your deficiency in self-control.

but that, by equalization of burdens, your superfluity having in the present emergency supplied their deficiency, their superfluity may in turn be a supply for your deficiency later on, so that there may be equalization of burdens.

because on account of the work of the Christ he drew near to death, having hazarded the life that he might fill up your deficiency of service unto me.
