2 Kings 3:20

when the meat offering was offered R.V. about the time of offering the oblation. The term meat offeringhas become misleading to modern English readers, because it would now imply that flesh of some kind formed a part of the offering; whereas the oblation [minchah here spoken of consisted (see Leviticus 2:1) of fine flour, oil and frankincense. Hence R.V. has rendered the word very frequently -meal offering", and in some places as here, where there was no need to be specific, by -oblation". The time of the offering was as soon as possible after day-dawn. In a similar manner the time selected by Elijah (1 Kings 18:36) for offering his prayer to God on Carmel was at the time of the offering of the evening oblation. Thus in both cases God's intervention was linked to the worship at Jerusalem. -Elijah fetched down his fire at the hour of the evening sacrifice, Elisha fetched up his water at the hour of the morning sacrifice. God gives respect to His own hours for the encouragement of our observation. If His wisdom hath set us any peculiar times, we cannot keep them without a blessing" (Bp Hall).
