Shall know the Lord; shall acknowledge, and love, and serve him; for words of knowledge in Scripture commonly include affection and practice, as hath been often observed.
Shall do sacrifice and oblation; shall worship God spiritually; which yet is signified by typical phrases, as it is Mal_1:11, and in many other places.
And perform it; they shall not only profess and promise piety, but shall seriously and diligently practise it.
