1: Διαταγή (Strong'S #1296 — Noun Feminine — diatage — dee-at-ag-ay' )

an ordinance, e.g.,  Romans 13:2 (cp. diatasso, "to appoint, ordain"), is rendered "disposition" in   Acts 7:53; RV, "as it (the law) was ordained by angels" (marg., "as the ordinance of angels;" lit., "unto ordinances of angels"). Angels are mentioned in connection with the giving of the Law of Moses in  Deuteronomy 33:2 . In  Galatians 3:19;  Hebrews 2:2 the purpose of the reference to them is to show the superiority of the Gospel to the Law. In   Acts 7:53 Stephen mentions the angels to stress the majesty of the Law. See Ordain , Ordinance.

Charles Buck Theological Dictionary [4]

That temper of mind, which any person possesses. In every man, says lord Kaims, there is something original that serves to distinguish him from others, that tends to form a character, and to make him meek or fiery, candid or deceitful, resolute or timorous, cheerful or morose. This original bent, termed disposition, must be distinguished from a principle; the latter signifying a law of human nature makes part of the common nature of man; the former makes part of the nature of this or that man.
