Isaiah 56

7. Even them--( Ephesians 2:11-13 ).
to my holy mountain--Jerusalem, the seat of the Lord's throne in His coming kingdom ( Isaiah 2:2 , Jeremiah 3:17 ).
joyful--( Romans 5:11 ).
burnt offerings . . . sacrifices--spiritual, of which the literal were types ( Romans 12:1 , Hebrews 13:15 , 1 Peter 2:5 ).
accepted--( Ephesians 1:6 ).
altar--( Hebrews 13:10 ), spiritually, the Cross of Christ, which sanctifies our sacrifices of prayer and praise.
house . . . for all people--or rather, "peoples." No longer restricted to one favored people ( Malachi 1:11 , John 4:21 John 4:23 , 1 Timothy 2:8 ). To be fully realized at the second coming ( Isaiah 2:2-4 ). No longer literal, but spiritual sacrifice, namely, "prayer" shall be offered ( Psalms 141:2 , 51:17 , Malachi 1:11 , Matthew 21:13 ).

8. Jehovah will not only restore the scattered outcasts of Israel ( Isaiah 11:12 , Psalms 147:2 ) to their own land, but "will gather others ('strangers') to him (Israel), besides those gathered" (Margin, "to his gathered"; that is, in addition to the Israelites collected from their dispersion), ( John 10:16 , Ephesians 1:10 , 2:19 ).

9. beasts--Gentile idolatrous nations hostile to the Jews, summoned by God to chastise them ( Jeremiah 12:7-9 , 50:17 , Ezekiel 34:5 ): the Chaldeans and subsequently the Romans. The mention of the "outcasts of Israel" ( Isaiah 56:8 ) brings in view the outcasting, caused by the sins of their rulers ( Isaiah 56:10-12 ).
to devour--namely, Israel.

10. His watchmen--Israel's spiritual leaders ( Isaiah 62:6 , Ezekiel 3:17 ).
dumb dogs--image from bad shepherds' watchdogs, which fail to give notice, by barking, of the approach of wild beasts.
blind--( Matthew 23:16 ).
sleeping, lying down--rather, "dreamers, sluggards" [LOWTH]. Not merely sleeping inactive, but under visionary delusions.
loving to slumber--not merely slumbering involuntarily, but loving it.

11. greedy--literally, "strong" (that is, insatiable) in appetite ( Ezekiel 34:2 Ezekiel 34:3 , Micah 3:11 ).
cannot understand--unable to comprehend the wants of the people, spiritually: so Isaiah 56: Isaiah 56:10 , "cannot bark."
look to . . . own way--that is, their own selfish interests; not to the spiritual welfare of the people ( Jeremiah 6:13 , Ezekiel 22:27 ).
from his quarter--rather, "from the highest to the lowest" [LOWTH]. "From his quarter"; that is, from one end to the other of them, one and all ( Genesis 19:4 ).

12. fetch wine--language of the national teachers challenging one another to drink. BARNES translates, "I will take another cup" ( Isaiah 5:11 ).
to-morrow, &c.--Their self-indulgence was habitual and intentional: not merely they drink, but they mean to continue so.
