John Trapp on Psalms 42:6

Verſ. 6. O my God, my ſoul is caſt down within me] Though before he had ſchooled himſelf out of his diſtem pers, yet now he is troubled again: ſuch are the viciſſitudes and interchanges of joy, and ſorrow, that the Saints are here ſubject unto: as ſoon as the Spirit gets the better, as ſoon the Fleſh; ſometimes good affections prevail, ſometimes unruly paſſions. Affections are the wind of the ſoul, paſſions the ſtorm. The ſoul is well carried, when neither ſo becalmed that it moves not when it ſhould, nor yet toſſed with tempeſts to move diſorderly.

Therefore will I remember thee from the Land of Jordan] That is, ſaith one, I will call to minde former experiments there, and take comfort. Or, I will remember thee, as I may, here at Mahanaim beyond Jordan, under the mount Hermon, and that other little Hill (where I have found thee, in my meditations, and prayers, propitious unto me) though I cannot now worſhip thee in the beauty of holineſs, being driven out by my ungracious Son Abſolom, from the place where thine honour dwelleth.
