יִזְכֹּ֥ר כָּל־מִנְחֹתֶ֑ךָ וְעוֹלָתְךָ֖ יְדַשְּׁנֶ֣ה סֶֽלָה׃
Receive the memorial of all thy meal-offerings, And accept the fat of thy burnt-sacrifice; Selah
Rashi on Psalms
your meal offerings...burnt offerings They are the prayers that you pray in battle.
Rashi on Psalms
fat Heb. ידשנה, an expression of fat, as (in Deut. 31:20): “and it will eat and be satisfied, and it will become obese (ודשן),” i.e., He will accept them [the prayers] willingly like fat burnt offering.
