In preparation for his “Palm Sunday entry” into Jerusalem, Our Lord did the following:
“When they had almost reached Jerusalem, as far as Bethphage and Bethany, near the Mount of Olives, Jesus sent on two of his disciples. “Go to the village facing you,” he said; “and, as soon as you get there, you will find a foal tethered, which no one has ever ridden; untie it, and bring it. And, if any one says to you ‘Why are you doing that?’, say ‘The Master wants it, and will be sure to send it back here at once.’”” Mark 11:1-3, TCNT.
In addition to obtaining the foal, God promised to send it back.
God had already heard a demand for return:
“And when she (Hannah) had weaned him, she took him up with her, with three bullocks, and one ephah of flour, and a bottle of wine, and brought him unto the house of the LORD in Shiloh: and the child was young. And they slew a bullock, and brought the child to Eli. And she said, Oh my lord, as thy soul liveth, my lord, I am the woman that stood by thee here, praying unto the LORD. For this child I prayed; and the LORD hath given me my petition which I asked of him: Therefore also I have lent him to the LORD; as long as he liveth he shall be lent to the LORD. And he worshipped the LORD there.” 1 Samuel 1:24-28, KJV.
Hannah had promised that, should she bear a son, same son would be dedicated to God’s service. She came through with her promise with one stipulation: that, once he had fulfilled God’s purpose, that she would get him back. It didn’t matter that it would be in Sheol, she wanted him back.
It’s amusing in a way to think that God, who owns it all, would either make a promise to return something or someone or honour such a request. But he does.
