Heb. 5:5, 8-9, (Italics Added),
5 So also Christ glorified not himself to be made an high priest; but he, (God the Father), that said unto him, Thou art my Son, today have I begotten thee.
8 Though he were a Son, yet learned he obedience by the things which he suffered;
9 And being made perfect, he became the author of eternal salvation unto all them that obey him;

5 And Zion cannot be built up unless it is by the principles of the law of the celestial kingdom; otherwise I cannot receive her unto myself.
6 And my people must needs be chastened until they learn obedience, if it must needs be, by the things which they suffer.
