Easton's 1897 Bible Dictionary:

Loan
   The Mosaic law required that when an Israelite needed to borrow,
   what he asked was to be freely lent to him, and no interest was
   to be charged, although interest might be taken of a foreigner
   (Ex. 22:25; Deut. 23:19, 20; Lev. 25:35-38). At the end of seven
   years all debts were remitted. Of a foreigner the loan might,
   however, be exacted. At a later period of the Hebrew
   commonwealth, when commerce increased, the practice of exacting
   usury or interest on loans, and of suretiship in the commercial
   sense, grew up. Yet the exaction of it from a Hebrew was
   regarded as discreditable (Ps. 15:5; Prov. 6:1, 4; 11:15; 17:18;
   20:16; 27:13; Jer. 15:10).

     Limitations are prescribed by the law to the taking of a
   pledge from the borrower. The outer garment in which a man slept
   at night, if taken in pledge, was to be returned before sunset
   (Ex. 22:26, 27; Deut. 24:12, 13). A widow's garment (Deut.
   24:17) and a millstone (6) could not be taken. A creditor could
   not enter the house to reclaim a pledge, but must remain outside
   till the borrower brought it (10, 11). The Hebrew debtor could
   not be retained in bondage longer than the seventh year, or at
   farthest the year of jubilee (Ex. 21:2; Lev. 25:39, 42), but
   foreign sojourners were to be "bondmen for ever" (Lev.
   25:44-54).


Bouvier's Law Dictionary, Revised 6th Ed (1856):

LOAN, contracts. The act by which a person lets another have a thing to be
used by him gratuitously, and which is to be returned, either in specie or
in kind, agreeably to the terms of the contract. The thing which is thus
transferred is also called a loan. 1 Bouv. Inst. n. 1077.
     2. A loan in general implies that a thing is lent without reward; but,
in some cases, a loan may be for a reward; as, the loan of money. 7 Pet. R.
109.
     3. In order to make a contract usurious, there must be a loan; Cowp.
112, 770; 1 Ves. jr. 527; 2 Bl. R. 859; 3 Wils. 390 and the borrower must be
bound to return the money at all events. 2 Scho. & Lef. 470. The purchase of
a bond or note is not a loan ; 3 Scho. & Lef. 469; 9 Pet. R 103; but if such
a purchase be merely colorable, it will be considered as a loan. 2 John.
Cas. 60; Id. 66; 12 S. & R. 46; 15 John. R. 44.
