Numbers 27:16
14 For in the wilderness of Zin when the community rebelled against me, you rebelled against my command to show me as holy before their eyes over the water—the water of Meribah in Kadesh in the wilderness of Zin.” 15 Then Moses spoke to the Lord: 16 “Let the Lord, the God of the spirits of all humankind, appoint a man over the community, 17 who will go out before them, and who will come in before them, and who will lead them out, and who will bring them in, so that the community of the Lord may not be like sheep that have no shepherd.” 18 The Lord replied to Moses, “Take Joshua son of Nun, a man in whom is the Spirit, and lay your hand on him;
Hebrews 12:9
7 Endure your suffering as discipline; God is treating you as sons. For what son is there that a father does not discipline? 8 But if you do not experience discipline, something all sons have shared in, then you are illegitimate and are not sons. 9 Besides, we have experienced discipline from our earthly fathers and we respected them; shall we not submit ourselves all the more to the Father of spirits and receive life? 10 For they disciplined us for a little while as seemed good to them, but he does so for our benefit, that we may share his holiness. 11 Now all discipline seems painful at the time, not joyful. But later it produces the fruit of peace and righteousness for those trained by it.
Notes and References
"... There are only 3 occasions in the NT where a concept of God's fatherhood appears which is without a Christological anchor. In Ephesians 3:14 God in his capacity as creator of the world is called "the Father ... (of) every family (patria) in heaven and on earth." In Hebrews 12:9 in his capacity as the creator of men's souls he is called 'Father of spirits.' In James 1:17 as creator of the stars, he is called 'Father of lights' (compare Apocalypse of Moses 36:3). It is possible that in these passages we see a trace of the Greek concept of the universal fatherhood of God ... The saying in Mark 14:38 that 'the spirit is willing but the flesh is weak' is not an OT quotation, and is thought by some to be Pauline or to come from Hel. Wisdom literature. But Taylor sees it anticipated by Numbers 27:16; Isaiah 31:3 ..."
