ציטירנדיקער פּירוש אויף דברים 13:19

To teach about the severance pay to a Hebrew slave that it must be five sela’im. . . I.e., it is written “empty-handed” here, relating to a donkey’s redemption. And it is written “empty-handed” in Devarim 13:15, relating to the severance pay of a Hebrew slave. Therefore, just as the redemption of a first-born [human being, as mentioned in v. 19,] is five sela’im, so the severance pay is five sela’im. Furthermore, the “empty-handed” of severance pay is at the beginning [of the section there], while [ostensibly] it should be at the end. Thus, we apply [the meaning of] “emptyhanded” [to all that follows it:] to “flocks,” to “winery” and to “threshing floor,” so that [the value of] five sela’im of each [of the abovementioned] kind should be [paid to the Hebrew slave].
