Thy strength; either,
1. This further act or instance of thy strength. Or rather,
2. Thy great power, which will more eminently appear in this than it hath done in former deliverances, as my danger is now greater, because this is a civil war, and the generality of mine own people are engaged against me, and my forces are very inconsiderable to theirs, and without thy help my case is desperate. To every one that is to come, i.e. to all succeeding generations, to whom I will leave a lasting monument of this glorious example of all-sufficiency, such as this Psalm is.
