Psalmen 105:20

Some of the psalms of praise are very short, others very long, to teach us that, in our devotions, we should be more observant how our hearts work than how the time passes and neither overstretch ourselves by coveting to be long nor over-stint ourselves by coveting to be short, but either the one or the other as we find in our hearts to pray. This is a long psalm; the general scope is the same with most of the psalms, to set forth the glory of God, but the subject-matter is particular. Every time we come to the throne of grace we may, if we please, furnish ourselves out of the word of God (out of the history of the New Testament, as this out of the history of the Old) with new songs, with fresh thoughts - so copious, so various, so inexhaustible is the subject.

Here is the preface (Psa 105:1-7) and the history itself in several articles. I. God's covenant with the patriarchs (Psa 105:8-11). II. His care of them while they were strangers (Psa 105:12-15). III. His raising up Joseph to be the shepherd and stone of Israel (Psa 105:16-22). IV. The increase of Israel in Egypt and their deliverance out of Egypt (v. 2…
