θάκησιν is in itself a correct form. θάκησις (θακέω) is (1) the act of sitting, (2) the means of sitting, as οἴκησις (οἰκέω) is (1) the act of dwelling, (2) the house. It is not found elsewhere, but cp.
, a twofold means of sitting in the sun. With the MS. reading θάκοισιν construe: — στῆσόν με ἢ πρὸς θάκοις βεβήλοις, εἴ τινα （θᾶκον） βλέπεις, etc. (We could not render εἴ τινα βλέπεις "if thou seest any man," since the need for a halt did not depend on that condition.) This is a construction much less clear and simple than that with θάκησιν. βεβήλοις may have induced the change of θάκησιν into θάκοισιν.
