Deuteronomy 10:17
15 However, only to your ancestors did he show his loving favor, and he chose you, their descendants, from all peoples—as is apparent today. 16 Therefore, circumcise your hearts and stop being so stubborn! 17 For the Lord your God is God of gods and Lord of lords, the great, mighty, and awesome God who is unbiased and takes no bribe, 18 who justly treats the orphan and widow, and who loves resident foreigners, giving them food and clothing. 19 So you must love the resident foreigner because you were foreigners in the land of Egypt.
1 Enoch 9:4
3 ⌈⌈And now to you, the holy ones of heaven⌉⌉, the souls of men make their suit, saying, "Bring our cause before the Most High.".' 4 And they said to the Lord of the ages: 'Lord of lords, God of gods, King of kings, 〈and God of the ages〉, the throne of Thy glory (standeth) unto all the generations of the ages, and Thy name holy and glorious and blessed unto all the ages! 5 Thou hast made all things, and power over all things hast Thou: and all things are naked and open in Thy sight, and Thou seest all things, and nothing can hide itself from Thee.
Notes and References
"... First, the writer reminds masters that “both their and your Master is in heaven,” whereas Colossians 4:1 simply has “you also have a Master in heaven.” Then he adds “and there is no partiality with him.” This thought has now been employed in connection with both groups in Ephesians (compare the equivalent “whether slave or free” in verse 8) in contrast to Colossians, where it is only used in regard to slaves. Mitton notes the appropriateness of the emphasis on impartiality being used in the address to masters rather than to slaves, since the higher up in social status people feel themselves to be, the more likely they are to expect to be accorded special consideration. The noun προσωπολημψία, “partiality” (compare Colossians 3:25; Romans 2:11), comes from the Hebraistic verbal expression πρόσωπον λαμβάνειν, “to show partiality, to judge purely at face value or on the basis of external factors” (compare Leviticus 19:15; Deuteronomy 10:17; Sirach 4:22, 27; 1 Esdras 4:39; Luke 20:21; Galatians 2:6; Barnabas 19:4; Didache 4:3). In the Old Testament and Jewish writings, impartiality in judgment is attributed to God (compare especially Sirach 35:11–13; Jubilees 5:15–19; Psalms of Solomon 2:18; compare also Romans 2:11; 1 Peter 1:17), but here and in Colossians this is transferred to Christ as Lord ..."
