John Wesley on Genesis 49:18

I have waited for thy salvation, Lord - If he must break off here, and his breath will not serve him to finish what he intended, with these words he pours out his soul into the bosom of his God, and even breaths it out. The pious ejaculations of a warm and lively devotion, though sometimes they maybe incoherent, yet they are not impertinent; that may be uttered affectionately, which doth not come in methodically. It is no absurdity, when we are speaking to men, to lift up our hearts to God. The salvation he waited for was, 1st, Christ, the promised seed, whom he had spoken of, Ge 49:10, now he was going to be gathered to his people, he breathes after him to whom the gathering of the people shall be. 2ndly, Heaven, the better country, which he declared plainly that he sought, Heb 11:13,14, and continued seeking now he was in Egypt.
