The Bible records that Isaac, the Son of Abraham, coming from the well Laharoi (which means well of the Living One who sees me) went out to meditate in the field at the eventide/evening (Genesis 16:14; Genesis 24:63).

From this account we can learn a few things – regarding the time and the place for our meditation.
1. Unlike most people’s habits of meditating in the morning,upon waking up, on matters of God, during one’s quiet time, Isaac, here establishes the fact that one can meditate at eventide (evening – as the darkness of the night sets in). In fact, the Psalmist writes, that Blessed in the man/woman, who meditates on the law of the Lord, day and night i.e., perpetually (Psalm 1:2).
2. Isaac, went into the field to meditate. The harvest is plentiful and the field is ready, not only for the harvest but also for our meditation. We ought to be meditating not, only in the security of our homes, but in our workplaces (fields that yield its harvest) as well. In other words, we need to be meditating at home and at work i.e., ubiquitously.

Points to ponder:
As spiritual darkness is fast approaching in the world we live in, if not already her, do we take time to meditate day and night, through dawn and dusk (eventide)? Secondly, are we going in our mission field, i.e., to the people around us, to meditate on God, at the break of day (dawn) and night (dusk)? Blessed is the man/woman who meditates on the law of the Lord, perpetually, ubiquitously.

Genesis 24:62-63 (KJV)
62 And Isaac came from the way of the well Lahairoi; for he dwelt in the south country.
63 And Isaac went out to meditate in the field at the eventide: and he lifted up his eyes, and saw, and, behold, the camels were coming.

Psalm 1:2 (KJV)
But his delight is in the law of the Lord; and in his law doth he meditate day and night.
