Psalms 141:2

2. Let my prayer be set forth before thee כון , koon, rendered “set forth,” here takes the sense of prepare, make ready, and, in Niphal future, “My prayers shall be prepared as incense.” The word is used in the Levitical technology, and refers to the careful preparation of the spices for holy incense, forbidden in common use. Exodus 30:34-38, where see note.

Before thee Better, Before thy face, in thy immediate presence, as in the holy place in the tabernacle.

As the evening sacrifice Hebrew, As the minchah of evening. The “minchah” was a bloodless offering, made in conjunction with bloody sacrifices, and always with the daily morning and evening lamb. The law respecting the minchah is given in Leviticus 2:0, and of the daily minchah, Exodus 29:38-42; Numbers 4:16, where see notes; in all which places, as also throughout Exodus, Leviticus, and Numbers, the word is rendered “meat-offering” in our English Bible. It was accounted “a sweet savour unto the Lord,” “most holy of the offerings of the Lord made by fire.” Leviticus 2:2-3. Its import was that of an azkarah, or memorial, and, from Exodus 29:42-46, a standing memorial throughout the generations of the perpetual presence of God with his people, and of the acceptance of their offerings. The psalmist, now in exile among heathen tribes, desires his worship may be as acceptable to God as the most holy services of the tabernacle.
