Adams on Psalm 141:2 & 147:3

141:2 As the evening sacrifice. This should be our daily service, as a lamb was offered up morning and evening for a sacrifice. But, alas! how dull and dead are our devotions! Like Pharaoh's chariots, they drive on heavily. Some, like Balaam's ass, scarce ever open their mouths twice.

147:13 He hath strengthened the bars of thy gates. Blessed is the city whose gates God barreth up with his power, and openeth again with his mercy. There is nothing can defend where his justice will strike; and there is nothing can offend where his goodness will preserve.

As quoted in Spurgeon's Treasury of David
