and wilt do that which is right in his sight;
which he shall see and order as fit to be done, and which was not to be disputed and contradicted by them:
and wilt give ear to his commandments, and keep all his statutes;
whether moral, ceremonial, or judicial, even all that either had been made known to them, or should be hereafter enjoined them; and this at Mount Sinai, where they received a body of laws, they promised to do; namely, both to hear and to obey, ( Exodus 24:3 Exodus 24:7 ) ( Deuteronomy 5:27 ) .

in any of the plagues inflicted on them, which they were witnesses of; from these they should be preserved, if obedient, but if not they must expect them, or what was similar to them, see ( Deuteronomy 28:27 ) ,
for I am the Lord that healeth thee;
both in body and soul; in body, by preserving from diseases, and by curing them when afflicted with them; and in soul, by pardoning their iniquities, which, in Scripture, is sometimes signified by healing, see ( Psalms 103:3 ) ( Malachi 4:2 ) .
