10. answered--The "angel of the covenant" here gives the reply instead
of the interpreting angel, to imply that all communications through the
interpreting angel come from Him as their source.
Lord hath sent to walk to and fro through the earth--If "Satan walks
to and fro in the earth" (implying restless activity) on errands of
mischief to God's people
(Job 1:7),
the Lord sends other angels to "walk to and fro" with unceasing
activity everywhere to counterwork Satan's designs, and to defend His
people
(Ps 34:7; 91:11; 103:20, 21;
Heb 1:14).
