Matthew Poole and continuators on Philippians 2:5

5 Let this mind be in you which was also in Christ Jesus.

Most Translations do express the causal or rather illative Greek, Particle, which ours doth here omit as an expletive. However the Apostle doth urge them to the exercise of self denial, mutual love, and an hearty condescention to one another from the great example of Jesus Christ, 2 Cor. 8, 9.

That so the mind which was in Christ, may be perceived in us, who if spiritual judge all things and have the mind of Christ, being enlightn'd by the same Spirit, we do judge as he coming in the flesh did, or, Let the same affection be found in you, that was really in him, Mat. 11.28. Ioh. 13.15.
