Thou shalt roast. The verb here primarily signifies to be matured by heat for eating; hence to be ripened as by the sun's heat (Genesis 40:10; Joel 3:13; Hebrews 4:13); and to be cooked, whether by boiling, seething, or roasting.
Here it is properly rendered by roast, as it was thus only that the Paschal lamb could be cooked. And go unto thy tents; return to thy place of abode; not necessarily to thy proper home (which might be far distant), but to the place where for the time thou hast thy lodging.
The phrase, "thy tents," which originally came into use while as yet Israel had no settled abodes in Canaan, came afterwards to be used as a general designation of a man's home or usual place of abode (cf.
1 Samuel 13:2; 2 Samuel 20:1; 1 Kings 8:66, etc.).
