  26 H7523 But if the manslayer H3318 shall at any time H3318 go H1366 beyond the border H5892 of his city H4733 of refuge, H5127 whither he fleeth,
  27 H1350 and the avenger H1818 of blood H4672 find H2351 him without H1366 the border H5892 of his city H4733 of refuge, H1350 and the avenger H1818 of blood H7523 slay H7523 the manslayer; H1818 he shall not be guilty of blood,
  28 H3427 because he should have remained H5892 in his city H4733 of refuge H4194 until the death H1419 of the high H3548 priest: H310 but after H4194 the death H1419 of the high H3548 priest H7523 the manslayer H7725 shall return H776 into the land H272 of his possession.
