Bereshit 22:9

ויעקד AND HE BOUND his hands and feet behind him. Hands and feet tied together is what is meant by עקידה “binding”. It is associated in meaning with עקודים in (Genesis 30:35) “[she-goats] that were streaked” — whose ankles were streaked white so that the place where they are bound could be plainly seen.

וַיָּבֹ֗אוּ אֶֽל־הַמָּקוֹם֮ אֲשֶׁ֣ר אָֽמַר־ל֣וֹ הָאֱלֹהִים֒ וַיִּ֨בֶן שָׁ֤ם אַבְרָהָם֙ אֶת־הַמִּזְבֵּ֔חַ וַֽיַּעֲרֹ֖ךְ אֶת־הָעֵצִ֑ים וַֽיַּעֲקֹד֙ אֶת־יִצְחָ֣ק בְּנ֔וֹ וַיָּ֤שֶׂם אֹתוֹ֙ עַל־הַמִּזְבֵּ֔חַ מִמַּ֖עַל לָעֵצִֽים׃

And they came to the place which God had told him of; and Avraham built an altar there, and laid the wood in order, and bound Yiżĥaq his son, and laid him on the altar upon the wood.
