  The aim of this paper is to deal with congruences for Jacobi sums of order
$2l^{2}$ over a finite field $\mathbb{F}_{q}, q=p^{r}$, $p^{r}\equiv 1\ (mod \
2l^{2})$, where $l>3$ and $p$ are primes. Further, we also calculate Jacobi
sums $J_{2l^{2}}(1,n)$ of order $2l^{2}$ in terms of Dickson-Hurwitz sums.
