To shew forth thy lovingkindness in the morning, and thy faithfulness every night,
Ver. 2. To show forth thy lovingkindness in the morning] Every morning, that God may have the firstfruits of the day, but especially on the sabbath morning, when we awake and rise, ad quietem et ad delicias animi et corporis, as Kimchi here hath it. The Jews bless God at the sabbath's coming in and going out.
And thy faithfulness in the night] Breaking our sleep for that purpose; yea, we must be in the fear of the Lord all the day long, Proverbs 23:17, how much more on the sabbath day! then our whole work must be ravished in spirit, doing no work, but such as whereby we either bless God or look to receive a blessing from God; none but such as wherein we would the Lord should find us at his coming; which Lactantius saith will be on the sabbath day.
