2 H85 And Abraham H559 said H2205 unto his oldest H5650 servant H1004 of his house, H4910 that ruled over H7760 all that he had, Put, H3027 I pray you, your hand H3409 under my thigh:

3 H7650 And I will make you swear H3068 by the Lord, H430 the God H8064 of heaven, H430 and the God H776 of the earth, H3947 that you shall not take H802 a wife H1121 unto my son H1323 of the daughters H3669 of the Canaanites, H7130 among H3427 whom I live:

4 H3212 But you shall go H776 unto my country, H4138 and to my relatives, H3947 and take H802 a wife H1121 unto my son H3327 Isaac.

5 H5650 And the servant H559 said H802 unto him, what if the woman H14 will not be willing H3212 to follow H310 me H776 unto this land: H7725 must I needs bring H1121 your son H7725 again H776 unto the land H3318 from from where you came?
