Targum sobre Levítico 8:15

And Mosheh killed the bullock: and Mosheh took the blood and put it upon the horns of the altar round about with his finger, and anointed the altar (to expiate it) from all double-mindedness, constraint, and force, from the thoughts of his heart, should any one of the princes of the sons of Israel have taken his separation from his brethren by violence, and brought it for the work of the tabernacle, or lest any one was found among the children of Israel who had it not in his heart to bring for the work, but heard the voice of the crier, and was constrained, and brought without willingness; therefore cleansed he it with the blood of the bullock, and poured the rest of the blood at the foot of the altar, and sanctified it to make atonement thereon.
