Psalms of Solomon 14:4
2 to those living in the righteousness of his commands, in the Torah that he commanded us for our lives. 3 The Lord's devout will live by it forever; his devout are the Lord's Paradise, the trees of life. 4 Their plant is rooted forever; they will not be pulled up as long as heaven shall last. 5 because God has reserved Israel for himself 6 But it is not so with sinners and criminals, who love the time enjoying their sins.
Ephesians 3:17
15 from whom every family in heaven and on earth is named. 16 I pray that according to the wealth of his glory he will grant you to be strengthened with power through his Spirit in the inner person, 17 that Christ will dwell in your hearts through faith, so that, because you have been rooted and grounded in love, 18 you will be able to comprehend with all the saints what is the breadth and length and height and depth, 19 and thus to know the love of Christ that surpasses knowledge, so that you will be filled up to all the fullness of God.
Notes and References
"... The point is reinforced by a sequence of forceful metaphors. These traditions of Jesus as Christ and Lord provide for the new community both a root for the new plant and a foundation for the new building. The verb 'cause to take root,' only here and in Ephesians 3:17 in the New Testament) vividly images the preaching / teaching as an effective sowing that results in a well-rooted plant (perfect participle; compare Sirach 24:12 - of wisdom; Psalms of Solomon 14:4; Odes of Solomon 38:17-22). The importance of deep roots was well understood in Jewish tradition (e.g., Jeremiah 17:8; Ezekiel 31:7; Sirach 40:15). Naturally the image is complementary to the 'fruit-bearing' metaphor of 1:10, which allows the same emphasis on a 'walk' determined by reference to 'the Lord.' Equally it makes a natural partner in Jewish tradition ..."
